Jailbreak iPhone, iPod Touch, iPad

DevTeam created a quick solution for jailbreaking an iPhone. It is called QuickPwn. It is in beta, so be careful. It will allow you to pwn (jailbreak) your device very quickly without restoring!

Who should use this tool? This is for those that are not planning to restore. It’s not clear what the activation state is after the process therefore, I only recommend this for those that have a contract carrier or an unlocked phone already.

If you are on a stock device and using AT&T or a contract carrier, this is the perfect jailbreak for you. You will not lose your contacts or have to do any backups. Finally, if you are going to restore anyway, especially if you need to unlock a 2g, you may as well use winpwn or such.

Currently QuickPwn requires your device to be running version 2.0.1 of the iPhone/iPod firmware. And it runs only on Windows. This requirement will change in a subsequent release.

You can download it here.

After successfull jailbreake of the IPhone/IPhone 3G with firmware 2.0 it is possible to install Cydia installer. And what is more exciting, there are many applications there, including Java.

This is a tutorial, that shows step by step how to install Java on the IPhone.

What we need is a working unlocked and jailbraked IPhone with Installer. I used latest firmware 1.1.4, unlocked, jailbreaked and customized by winpwn.

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 .

There are two steps:

Step 1: Go to Installer and install Mobile Terminal and Cydia Installer.

1. Go to Settings -> General -> Auto-Lock and set it to Never. This will avoid some troubles during installation.
2. Run Installer. Repository for Terminal should be already there (BigBoss), because it is in latest Community Sources.
3. Add repository http://apptapp.saurik.com for Cydia Installer and refresh
4. Go to Install -> System
5. Find Term-vt100 – Mibile Terminal App. I used version svn278. Install it.
6. Go to System again and find Cydia Installer – The Future of the IPhone. I used version 1.0. Install it.
7. Exit. Restart IPhone. Two icons for Terminal and Cydia should appear.

Here are some screenshots for Step1:

Step 2: Go to Cydia Installer and install Java.

1. Run Cydia Installer.
2. Go to Install – Java section. You will find many programms there.
3. Select IPhone/Java. It will install most of the needed packages, which includes vm, libraries, etc.
4. Click confirm and wait a little bit.
5. Go to Java section again and install Jikes package (itwill be probably the only one left). Jikes is a compiler.
6. Go to Installed Packages tab. Check that Classpath, IPhone/Java, JamVM, Jikes are installed. Several other packages will be there too (Java SQLite, JocStap, etc).
7. Exit Cydia and restart IPhone. Congratulations!!! You’re done installing Java.

That’s it. The tutorial about using all this stuff is here
