UPDATE: Please, consider reading our Jailbreak & Unlock FAQ, especially if you have questions or troubles.

This is a step-by-step tutorial. If you have iPhone 3G this guide will help you jailbreak and activate the device. For iPhone 2G it will also perform the unlock.

I recommend using 2.2 firmware, because iPhone 3G unlock is avaliable now. But you can use it with old v2.1, v2.0.1 and v2.0.2.

PdaNet updated to version 1.33. This tool allows you to connect any desktop or notebook to internet through iPhone 3G. Here is a changelog:

This application is avaliable via Cydia Installer for jailbreaked iPhones.

JocStrap - Java/Objective-C connection library, new version 1.0.2466-18 (was 1.0.2466-17).

Jocstrap is a bridge between Java and Objective-C. This is needed to write Java applications for IPhone. Just in case you don't have Cydia and Java installed on your IPhone, follow these instructions: Tutorial: install Java on the IPhone.

There was a method to use IPhone's internet connection on a desktop (Get internet on a desktop or notebook through IPhone 3G), now there is an officail one:

NetShare is one app we never thought would make it onto the official iPhone App Store. The $9.99 application promises to allow you to share your iPhone's network connection with your computer. All it does is set up a SOCKS5 proxy for you to get your laptop/computer online through use of the 3G/EDGE connection. Does it work? Yes. Yes it does, much to our surprise. EDGE works just fine, although Mahoney says it's slow as balls. 3G impressions in a sec. Be careful of how much bandwidth you're using, since your provider probably makes a frowny face at you using their network to power your laptop, however "unlimited" your plan may be. How this got passed Apple and AT&T who knows.

Link to AppStore: NetShare. Tutorial is here: NetShare HOW TO.

Update 1: There are some bugs with iPhone 3G.

Update 2: The application is gone. Now we're getting the message that it's not available in the US store

Update 3: Just an official reply from Nullriver:

"We're not quite sure why Apple took down the application yet, we've received no communication from Apple thus far. NetShare did not violate any of the Developer or AppStore agreements. We're hoping we'll get some feedback from Apple tomorrow. Sorry to all the folks that couldn't get it in time. We'll do our best to try to get the application back onto the AppStore if at all possible. At the very least, I would hope Apple will allow it in countries where the provider does permit tethering."

Update 4: The application re-appeared in iTunes. It is avaliable through direct link: NetShare.

Update 5: It's gone.. again.

Thanks to Dev Team and the porting work of Jay Freeman as well as the authors of 3Proxy, it is now possible to "tether" your iPhone 3G and use its Internet connection on your laptop.

Warning - Tethering your iPhone is against the iPhone data plan terms. AT&T could slap you with huge fees if you overuse this. I recommend only using it during emergencies.

Here is a basic plan (by the way, this should work for old IPhone also):

• Jailbreak your iPhone 3G
• Install 3Proxy and Terminal
• Create an ad-hoc Wi-fi network using your laptop
• Join the network with your iPhone
• Find the iPhone's IP address
• Open Terminal and run the proxy program
• Open Safari on your iPhone and open a web page
• Configure your browser to use the proxy

Later we'll discuss it with more details.

Just in case you don't have Cydia and Java installed on your IPhone, follow these instructions: Tutorial: install Java on the IPhone.

This is another simple Java GUI application for the IPhone/IPod from Java Flavor Weblog. It simply shows Java system information on iPhone/iPod touch. It uses Java, JocStrap and GNU Classpath.

This application can be installed through Installer. Just add the repository http://javaflavor.cocolog-nifty.com/apptapp/. The application can be found in Java section and is called JavaSysInfo. Or just download it here: javasysinfo-092.zip. The package includes compiled class files, source java files and runnable script with an icon. Here are the sources: JavaSysInfo and JavaSysInfoController.

Note that JocStrap applications, including JavaSysInfo, currently require JocStrap, UICaboodle, JamVM, GNU Classpath, GNU Classpath Tools, Apache APR, libffi and BSD Subsystem. In most cases all this was installed during Java on IPhone installation.

During Java instalation there was sample programm installed. It is called HelloJava. It is a bit more complicated than basic console HelloWorld-type application, that we tried to compile and run during this tutorial. HelloJava uses gui and SQLite. It uses several classes, that are bridges to IPhone's functionality (GUI, sound, SQL, etc). But all that it does is it reads contacts' first and last names from IPhone's database (throught SQL select statement) and shows them on the screen in GUI mode. It also produses simple sound in the end.

Here is a screenshot of the icon and application itself:

The application consists of several files:

First of all I'd like to say we all want to use legal IPhones and operators. So everything written below is for testing purposes only . Hopefully this technology will be avaliable on all IPhones sold worldwide. You also might need to recover your IPhone, so make sure you backed up all your data. I personally did everything without any problems and needs to recover. Everything you do is your responsibility, etc...

So let's start, because it's worth it! It's just one evening and you will be able to create your personal Java application, compile and run it on the IPhone, and amaze all your friends .
