Wap Facebook Chat.jar Today

File Format (.jar): A .jar file is a Java Archive. In the era before app stores, mobile phones running the J2ME (Java 2 Micro Edition) platform used these files to run third-party software.

WAP (Wireless Application Protocol): "WAP" was the standard for accessing the internet on mobile phones with limited hardware. A "WAP Facebook Chat" app was essentially a bridge that let these limited devices communicate with Facebook's servers.

Target Devices: These apps were primarily used on brands like Nokia (e.g., C2-01, C5), Sony Ericsson, and BlackBerry.  "Facebook for Every Phone" 

In 2011, Facebook officially launched a Java app called Facebook for Every Phone to reach the "next billion" users in emerging markets. 

Functionality: It provided a lightweight News Feed, photo uploading, and a dedicated inbox for Facebook Messages.

Optimization: Because these phones had very little memory and slow data speeds, the .jar app was highly optimized to use minimal data while providing a smoother experience than the mobile web browser.  Third-Party vs. Official Apps 

While Facebook had an official Java app, many users sought "wap facebook chat.jar" files from third-party sites like GetJar or BoostApps. 

Third-Party Variations: Some versions were modified (modded) to hide virtual keypads or bypass specific carrier restrictions.

Security Risks: Downloading .jar files from unofficial sources was a common way for users to accidentally install malware or have their login credentials phished, as these files could be easily altered.  The Transition to Messenger 

By 2014, Facebook began moving away from integrated apps and required users to download a standalone Messenger app. For older hardware, they eventually released Messenger Lite in 2016, which effectively replaced the need for the older Java .jar chat applications. 

Report: WAP Facebook Chat.jar Analysis

Introduction

In the early 2000s, mobile internet access started gaining popularity, and with it, mobile messaging applications began to emerge. One such application was WAP Facebook Chat.jar, a Java-based chat client designed for mobile devices. This report provides an analysis of WAP Facebook Chat.jar, its features, functionality, and impact on mobile communication.

What is WAP Facebook Chat.jar?

WAP Facebook Chat.jar is a Java Archive (JAR) file that enables Facebook chat functionality on mobile devices via WAP (Wireless Application Protocol) technology. WAP allowed mobile devices to access internet services, including email, browsing, and messaging. The JAR file contains the necessary code to run the chat client on Java-enabled mobile phones.

Key Features

1. Facebook Chat Integration: WAP Facebook Chat.jar allows users to access Facebook's chat service directly from their mobile device, enabling them to send and receive text messages with friends.
2. Java-based: The application is built using Java, making it compatible with a wide range of mobile devices that support Java.
3. WAP Technology: The client uses WAP to connect to the internet and retrieve chat data, ensuring seamless communication.

Functionality

Upon launching the application, users are prompted to enter their Facebook login credentials. Once authenticated, the client displays a list of friends, allowing users to select and chat with individual contacts. The interface is simple and text-based, with features like:

1. Text-based chat: Users can type and send messages to friends.
2. Friend list: Displays a list of online friends.
3. Message notification: Alerts users to new incoming messages.

Impact on Mobile Communication

WAP Facebook Chat.jar played a significant role in the early adoption of mobile messaging services. By providing a simple, accessible chat client, it:

1. Extended Facebook's reach: Enabled users to access Facebook's chat service on-the-go.
2. Paved the way for mobile messaging apps: Popularized the concept of mobile messaging, influencing the development of later apps like WhatsApp, WeChat, and Facebook Messenger.
3. Showcased WAP technology: Demonstrated the potential of WAP for mobile internet access.

Legacy and Current Status

As mobile technology evolved, WAP Facebook Chat.jar became less relevant. Facebook eventually discontinued support for the WAP-based chat client, and modern mobile devices no longer support Java-based applications. Today, Facebook offers more advanced, native mobile apps for messaging, which have largely replaced WAP-based services.

Conclusion

WAP Facebook Chat.jar represents an early attempt to bring social media and messaging to mobile devices. Although it is no longer supported, its influence on the development of mobile messaging services and the popularization of WAP technology cannot be overstated. This report provides a nostalgic look at the beginnings of mobile communication and the evolution of messaging services.

Title: The Last .jar File

Year: 2011

Rohan pressed the center button on his Nokia 2690. The tiny screen glowed blue. On the memory card, one file stood out among the grainy wallpapers and polyphonic ringtones: wap_facebook_chat.jar.

It had taken him forty-five minutes last night to download it over GPRS. The progress bar had crawled byte by byte, and he'd held the phone near the window, praying no one would call and break the connection. But it was done. It was his.

He clicked "Install."

The phone asked: Allow application to access network?
Yes.
Allow application to read phone status?
Yes.

The icon appeared: a blue 'f' on a tiny globe. Rohan opened it. A loading screen with a spinning circle—two minutes that felt like hours. Then: a stripped-down, white-and-blue login page, no images, no CSS. Just text boxes.

Username:
Password:

He typed slowly, using multi-tap. Praying again that the phone's small RAM wouldn't crash.

Login successful.

The chat list loaded:

• Mom (offline)
• Aarav (idle)
• Neha (Online)

His heart beat faster. There she was. Neha. Her little green dot—the first time he'd seen it this term. They'd passed notes in class, but now, after school, through this janky WAP chat, they could talk without anyone listening on the landline.

His thumb glided over keys:
u der?

Press "Send." The spinning wheel returned. Five seconds. Ten seconds.

The reply came:
yea. thought u were busy

He typed back: no. got the wap app finally

lol ancient tech

but it works

Silence for a moment. Then:

meet @ the gully behind school tmrw?

Rohan stared at the screen. The phone's battery was down to one bar. His mom would call him for dinner any minute. Outside, a monsoon drizzle started against the windowpane.

He wrote: yes. 4pm

He pressed Send, and just as the message status changed to "Delivered," the phone beeped—low battery warning. The screen dimmed. The chat window vanished back to the homescreen.

He smiled anyway.

The next day, behind the school gully, standing in muddy shoes with rain dripping off a broken umbrella, Rohan waited. At 4:02, Neha walked around the corner. No phone in her hand. Just a shy smile.

"So," she said. "Your WAP chat worked?"

"It worked," he said.

"Good. Now you don't have an excuse to forget our plans."

She handed him half of a chocolate bar. They walked through the empty lanes, not talking much, while in his pocket, the Nokia slept—dark screen, drained battery, but wap_facebook_chat.jar still installed, waiting for the next time.

It would be a long time before either of them realized: that tiny .jar file was probably the most romantic thing they'd ever use.

End of story.

The search for "wap facebook chat.jar" takes us back to a nostalgic era of mobile technology—the mid-to-late 2000s—when Java-enabled feature phones reigned supreme before the smartphone revolution. At its core, this keyword refers to a specialized application designed for early mobile devices to access Facebook’s messaging services via Java Micro Edition (J2ME). Understanding the Technology

In the era of Nokia, Sony Ericsson, and Motorola Razr, apps weren't downloaded from "stores" but were often shared as .jar (Java Archive) and .jad (Java Application Descriptor) files.

WAP (Wireless Application Protocol): This was the standard for accessing information over a mobile wireless network before modern mobile broadband. "WAP Facebook" was a lightweight, text-heavy version of the social network.

The .jar File: This was the executable file that contained the application's code and resources. A "Facebook Chat .jar" was a standalone IM client that allowed users to stay connected without needing a full-sized PC or a modern smartphone. Why "WAP Facebook Chat .jar" Was Popular

Before the unified Facebook Messenger app, staying online was a challenge for users on limited data plans or older hardware.

Low Data Consumption: These Java apps were designed to be incredibly efficient, using minimal data to send and receive text-based messages.

Hardware Compatibility: J2ME was designed for small devices with limited processor power and tiny memory footprints.

Background Connectivity: Some early .jar clients used clever tricks like long polling or persistent connections to simulate the "push notifications" we take for granted today. The Evolution of Mobile Facebook

As mobile technology advanced, the way we chat on Facebook underwent massive shifts:

Mobile Web Browsing: Users first accessed Facebook through m.facebook.com, which offered a basic chat interface.

Dedicated Java Apps: Developers created third-party .jar apps, and eventually, Facebook released "Facebook for Every Phone," a J2ME app that brought a more modern experience to over 3,000 different phone models.

The Rise of Messenger: With the advent of Android and iOS, Facebook moved to dedicated platform-specific apps. Modern Messenger now supports high-definition video calls, encrypted chats, and AI-driven features. Can You Still Use .jar Chat Apps Today?

While you can still find legacy .jar files on various archive sites, using them to chat on modern Facebook is nearly impossible for several reasons:

Security & Encryption: Modern Facebook uses advanced end-to-end encryption and security protocols that old Java apps cannot process.

API Changes: Facebook has long since retired the legacy APIs that these early chat clients relied on.

Emulation: If you're feeling nostalgic, you can use tools like J2ME Loader on Android to run old Java games and apps, but live chat features will likely fail to connect.

For those looking to relive the past, the wap facebook chat.jar remains a symbol of a time when the internet was just beginning to fit into our pockets, one kilobyte at a time.

The year was 2009, and the world was glowing through a two-inch screen.

sat at the back of the bus, his thumb hovering over the tactile keypad of his Nokia 5130 XpressMusic. The air was thick with the smell of damp upholstery and diesel fumes, but Leo was elsewhere. He was staring at a pixelated loading bar that felt like it was moving through molasses. He was trying to open facebook_chat.jar

In those days, Facebook wasn't an "app" you just had; it was a treasure you hunted for on shady WAP forums. You had to find the right

file—the Java executable—that wouldn't crash your phone or steal your prepaid credits. This specific version was the holy grail: it promised real-time messaging without having to refresh a browser page.

The bar hit 100%. The screen flickered, a tiny blue header appeared, and then—magic. A list of names with green dots. Maya is online.

Leo’s heart did a slow roll. Maya had moved three towns away over the summer. In 2009, three towns away might as well have been the moon. They couldn't afford long-distance calls, and SMS was ten cents a pop—a luxury his allowance couldn't sustain.

He clicked her name. The interface was clunky, the font was blocky, and he had to press the '7' key four times just to get the letter 'S', but he typed: “Hey. Is it working?”

He waited. The edge of the screen showed the "E" icon for EDGE data—the fastest connection he could hope for, which was still agonizingly slow. A minute passed. The bus hit a pothole, jarring his hand. Then, a tiny sound, tinny and digital.

“Leo! Omg yes. I can’t believe u found a version that works on my phone too.”

For the next forty minutes, the bus disappeared. Leo didn't feel the plastic seat or hear the engine’s whine. He was suspended in a blue-and-white digital void. They talked about the new school, the songs they were Bluetooth-ing to each other, and the strange ache of being apart.

Every message was a battle against a "Connection Lost" popup. Every reply was a victory. He watched his "GPRS Data" counter tick up, knowing he was burning through his $5 recharge, but he didn't care.

As the bus pulled into his stop, Leo typed one last message:

“Don’t log off. I’ll be back as soon as I finish my homework.” He snapped the phone shut, the mechanical

sounding like a period at the end of a sentence. He stepped off the bus, the cold air hitting his face, feeling like a pioneer who had just mastered fire. wap facebook chat.jar

He didn't have a smartphone, a high-speed data plan, or a sleek interface. He had a 240x320 pixel window to the person he missed most, wrapped in a 400KB Java file. And for now, that was the entire world. of mobile tech or move the story into a different genre , like a tech-thriller?

First, I need to explain what WAP is and its relevance. Then, clarify what a .jar file is in this context. Maybe they're looking for a way to chat with Facebook friends without internet data using Java on a feature phone. But I should check if such an application exists. Wait, Facebook has moved away from Flash and relies heavily on online services. Maybe the user is trying to access an older method of Facebook chat via WAP.

I should mention that Facebook's primary chat service is over XMPP and uses web protocols. So a .jar file for offline chat might not exist. Also, security issues: using third-party .jar files can be risky if not from trusted sources. Need to highlight that Facebook might not support this and using such files could be against their terms of service.

Also, modern Facebook uses HTTPS, and older WAP might not be compatible. Suggest using official methods like the Facebook app or Messenger. If they still want a .jar, maybe point out security concerns and alternative solutions. Make sure the information is accurate, not promoting insecure practices, and guides them to safe, official methods.

The request for "WAP Facebook Chat.jar" appears to reference a Java-based application (.jar file) for accessing Facebook chat via WAP (Wireless Application Protocol), typically used on older mobile devices (e.g., 2G feature phones). Here's an informative breakdown of the context, limitations, and modern alternatives:

Part 5: The Decline – Why We Stopped Searching

By 2013, the era of "wap facebook chat.jar" was over.

The Digital Archaeologist’s Guide: Unearthing “wap facebook chat.jar”

In the mid-2000s, a specific string of text was the golden key to social connection for millions of users across emerging markets. That string is: "wap facebook chat.jar" .

To a teenager in 2025, this looks like a cat walked across a keyboard. But to someone who grew up with a Nokia 6300, a Sony Ericsson W810i, or a BlackBerry Curve, those 20 characters evoke a powerful sense of nostalgia. They represent a bizarre, ingenious technological era where speed was measured in kilobits per second (kbps) and social media had to be squeezed into a 200-kilobyte file.

This article is a deep dive into the history, the technology, the risks, and the legacy of the .jar file that let the world chat on Facebook.

Write-Up: Understanding "wap facebook chat.jar"

The "WAP" Confusion

The keyword includes "wap," which stands for Wireless Application Protocol. Technically, WAP was a dated standard from the early 2000s for browsing stripped-down internet. By the time Facebook Chat was popular, we were using 2.5G (EDGE) and 3G. However, users still used "WAP" as a catch-all term for "mobile internet that is cheap and low-data."

So, "WAP Facebook Chat" meant: Facebook’s mobile interface, optimized for slow networks, packaged into a downloadable app.

Review — "wap facebook chat.jar"

Summary

• "wap facebook chat.jar" appears to be a Java ME (J2ME) midlet packaged as a .jar intended for feature phones to access Facebook chat via WAP-era protocols. It’s an outdated, niche app for legacy devices.

Functionality (what it likely does)

• Connects to Facebook’s chat using HTTP/WAP endpoints or an older API.
• Provides a simple text-based chat UI, contact list, and message sent/receive features.
• Minimal multimedia support; no modern features like read receipts, reactions, or media uploads.
• Requires manual configuration of network/WAP settings on many carriers.

Pros

• Very small download size and low resource usage — suitable for basic feature phones.
• Simple interface that’s easy to navigate on numeric-keypad devices.
• Useful in areas or devices where modern smartphone apps aren’t available.

Cons / Risks

• Obsolete: Facebook changed APIs and authentication flows many times; such clients often stop working.
• Security: Likely uses insecure connections (HTTP) or non-OAuth authentication; credentials may be exposed.
• Privacy: Unknown developer and source — could be malware, credential-harvesting, or include spyware.
• Compatibility: Requires Java ME runtime; modern Android/iOS devices won’t run it.
• No updates/support: Unmaintained software is vulnerable and unreliable.

Installation & Usage Notes

• Only install on expendable/legacy devices you control; avoid entering real Facebook credentials if the app’s source is untrusted.
• If you must test, create a throwaway Facebook account and use a unique password.
• Check for a matching .jad file and correct MIDlet-Name/Permissions before installing.
• Prefer modern, official Facebook apps or the mobile web (m.facebook.com) on capable devices.

Verdict

• Not recommended for regular use. It can be a curiosity or useful on legacy phones, but due to compatibility, security, and privacy concerns, prefer official, updated clients or the mobile web.

The Era of Wap Facebook Chat.jar: A Nostalgic Deep Dive In the early to mid-2010s, before smartphones became universal, a specific file type—the .jar—was the lifeblood of mobile social networking. For millions of users on Nokia, Samsung, and Sony Ericsson feature phones, the "Wap Facebook Chat.jar" application was the primary bridge to the digital world. What Was "Facebook Chat.jar"?

Technically, .jar files are Java Archive files used by the Java ME (Micro Edition) platform, also known as J2ME. Because early mobile hardware lacked the power to run complex modern browsers, lightweight Java apps were designed to handle specific tasks like messaging and news feeds.

The most famous of these was the "Facebook for Every Phone" app, which Facebook claimed was compatible with over 2,500 different phone models. Key Features of the Legacy Java App

These applications were marvels of efficiency, often weighing in at less than 150 KB. Despite their size, they offered a robust suite of tools:

Real-Time Chat: The core appeal was the ability to send and receive messages without refreshing a WAP page.

News Feed Access: Users could view status updates, like posts, and leave comments.

Photo Uploads: Even on low-spec cameras, the app allowed users to share photos directly from their phone's gallery to their wall.

Data Savings: Because the app only transmitted essential data rather than full webpage code, it was much cheaper to use on limited data plans. How the Technology Worked

Unlike modern apps that use high-speed 4G/5G connections, these J2ME apps relied on socket connections or HTTP polling.

The Client: The .jar file acted as the user interface on the phone.

The Server: It connected to Facebook's backend servers, which would push message notifications to the client whenever a new chat was received.

WAP Integration: "Wap" (Wireless Application Protocol) served as the gateway, allowing these early mobile devices to access the broader internet via their carrier's network. The Transition to Standalone Messenger

The era of the all-in-one Facebook Java app began to fade around 2014. Facebook made a strategic pivot to unbundle its services, eventually requiring users to download a standalone Messenger app for mobile chat. While this move was controversial at the time, it allowed for higher-quality features like VOIP calling, stickers, and eventually end-to-end encryption.

The phrase "wap facebook chat.jar — deep paper" appears to refer to a legacy mobile application file and a specific online repository or document. Understanding the Components WAP (Wireless Application Protocol):

If you are looking for this file to use on an old device, be aware of the following: Functionality:

Most of these legacy Java apps no longer work because Facebook has disabled the older APIs and chat protocols (like XMPP) they relied on. Security Risk: Downloading

files from unofficial "WAP" sources or third-party document sites is risky, as they can contain malware or phishing scripts designed for older mobile operating systems.

If you're trying to access Facebook chat on a modern device, the official Messenger app mobile website (m.facebook.com) are the only supported methods. Meta for Developers Are you trying to run this file on an emulator or looking for a specific document with that title? Karnataka Bank

The file icon was a pixelated coffee cup that had never looked right on a 1080p screen. It sat on the desktop of Jonas’s laptop, a relic named facebook chat.jar.

Technically, the file should have been dead. It was a Java ME application, designed for a world of plastic keyboards and 2G networks. But Jonas, a systems archivist with a penchant for digital necromancy, had spent three weeks trying to get it to run.

He wasn't interested in the history of social media. He was interested in the date: Last Modified: October 14, 2009. That was the day his brother, Eli, vanished. The police report said "missing person," the private investigator said "likely started a new life," but the family hard drive backup said Eli had been furiously typing on his Nokia brick phone until the battery died.

Jonas had found the .jar file buried in a dusty backup of Eli’s old SIM card data. It wasn’t the official Facebook app. The filename was slightly off: wap facebook chat.jar. It felt like a bootleg, a third-party client used by kids who didn’t want to pay for data.

Jonas fired up the Java emulator. A black rectangle the size of a postage stamp appeared on his screen, emulating a Nokia N95. The interface loaded with a screech of synthetic dial-up audio.

The color scheme was wrong. It wasn’t the standard Facebook blue. It was a deep, bruised purple. The text was jagged, rendering in a font that looked like it had been scratched onto the screen with a knife.

CONNECT? the screen flashed. Y/N

Jonas hit 'Y'.

The emulator didn't use his modern fiber optic connection. It seemed to be tunneling through something else, something slow. The loading bar moved with the agonizing lag of 2009. The cursor blinked once. Twice. Then, the chat interface popped up. File Format (

It was empty.

Then, a sound—a low, distorted bloop that made Jonas jump. A contact appeared at the top of the list.

E_Mann98

Jonas froze. It was Eli’s old handle.

His hands trembled over the keyboard. He navigated the cursor over the name. The options menu appeared: View Profile, Send Message, Delete.

He selected Send Message.

Jonas: Eli? Is that you?

He waited. The lag was excruciating. The little "sending" icon in the top corner—a rotating hourglass—spun for nearly a minute.

Then, the screen flickered. A message appeared. It wasn't from Eli. It was a system notification in bright red text.

SERVER STATUS: ARCHIVE MODE. 1 USER DETECTED IN BUFFER.

Jonas frowned. Archive mode?

Another bloop.

E_Mann98: jon? is the connection secure? dont use the wifi. use the wap. the wap is safe.

Jonas leaned in, his heart hammering. This wasn't an archive. This was live. But how? Eli’s account had been memorialized years ago.

Jonas: Eli, where are you? Everyone thinks you’re dead.

E_Mann98: im not dead. im stuck in the load. jon, you have to listen. the app isnt what you think it is. did you download the map pack?

Jonas: What map pack? Eli, come home.

E_Mann98: theres no home. not anymore. the .jar is a trap. it compresses data. it compressed me.

Jonas stared at the screen. The text was coming in faster now, the typos increasing, as if the person on the other end was running out of time.

E_Mann98: i was trying to bypass the data cap. i found a backdoor in the handshake protocol. i thought i could get free internet forever. but the protocol... it requires a user signature to balance the equation. it took mine.

Jonas: You’re inside the file?

E_Mann98: im part of the code now. im the handshake. every time someone logs in, they pass through me. ive been talking to people for ten years, jon. but they never hear me. they just see a chat log. they think im a bot.

Jonas: I can hear you. I’m pulling you out.

Jonas frantically googled how to decompile a .jar file. He downloaded a Java decompiler, dragging the wap facebook chat.jar file into the workspace. Lines of code spilled across his screen—manifest files, class files, resources.

He searched for text strings. He found the login protocols, the graphic assets for the purple background. Then, at the bottom of a file named UserSession.class, he found a massive block of encoded text. It wasn't binary. It was Base64.

He copied the block into a decoder. It translated into a single, repeating line of coordinates.

43.6126° N, 116.3915° W

It was a location in the desert, fifty miles from where Eli’s car had been found abandoned.

Jonas: Eli, I see the coordinates. Is that where your body is?

The chat window glitched. The purple background darkened to black. The cursor moved on its own.

SYSTEM: SESSION TIMEOUT IMMINENT. REFRESH TO PURCHASE MORE DATA.

Jonas: No! No, don’t go!

E_Mann98: jon dont refresh. DONT REFRESH. it costs a soul.

The screen began to shake violently within the emulator window. The text warped, the letters stretching vertically until they were unrecognizable lines.

E_Mann98: its not facebook. it never was. its a toll booth. delete the file. please. delete it before it takes you too. i love you bro.

The chat window turned white. A single popup appeared in the center of the emulated screen, rendered in that jagged, scratched font:

OUT OF MEMORY.

Jonas sat in the silence of his apartment. The digital clock on his desktop read 3:00 AM. He reached for his mouse to close the emulator, but his hand stopped.

The OUT OF MEMORY message had vanished. The chat window was back. It was empty.

Then, his modern notification center—the one in the corner of his actual Windows desktop, not the emulator—pinged.

A new file had appeared in his Downloads folder.

wap facebook chat_v2.jar

It hadn’t been there a moment ago. The file size was larger. The "Last Modified" date read: October 14, 2024. Today.

Jonas looked at the emulator. The chat window remained empty, waiting. He knew he should delete it. He knew he should format the drive. But the cursor in the chat box was blinking, a steady, rhythmic heartbeat.

He had spent ten years looking for his brother. He had found him in a bottleneck of code, trapped in a mechanism that fed on connection.

Jonas opened the chat window on the new file. He began to type.

Jonas: I’m coming in. Save some bandwidth for me.

He double-clicked the new .jar file. The hourglass spun, and the world went pixelated purple.

Retro Computing

A small community of "dumbphone rebels" is reviving .jar files in 2025. Using phones like the Nokia 800 Tough or the Light Phone II, they sideload old Java clients to escape the dopamine slots of modern social media. They want the "chat only" experience. They want the 5KB/minute rhythm. They are, ironically, searching for the same file we hunted a decade ago. Facebook Chat Integration : WAP Facebook Chat

The "Digital Divide" Bridge

For millions of people in India, Indonesia, Brazil, and Nigeria, the .jar file wasn't just an app. It was their first access to the global internet. It allowed a farmer with a $20 phone to maintain a relationship with a cousin working in Dubai. It was a utility, not a luxury.

Official vs. Unofficial Versions

Interestingly, Facebook never released a spectacular native Java app. They relied on m.facebook.com (the mobile web portal). However, third-party developers built dedicated .jar wrappers.

• Official (Rare): A simple portal app that loaded m.facebook.com inside a Java web viewer. It was slow, but safe.
• Unofficial (Common): Apps like "Sociality" or "Froj" (Facebook + Twitter). These were reverse-engineered APIs. They were faster, lighter, and could run in the background, but they violated Facebook’s terms of service.
• The "Pure" Chat Client: Many .jar files were just chat clients. They stripped away the News Feed, photos, and profiles. All you saw was a green bubble list of online friends. For a user with a 10MB data plan, this was paradise.
