iPhone Guides. Posted on: February 26, 2009

The iPhone 2.2.1 OS has been jailbroken via PwnageTool 2.2.5 and QuickPWN 2.2! And, with the release of the iPhone 3G unlocking software, dubbed yellowsn0w, The iPhone 3G can now be unlocked to work with any GSM network in the world. In order to use yellowsn0w, you first have to upgrade to the 02.28.00 baseband (2.2 Firmware). If you attempt to run yellowsn0w on anything but this baseband, the app will silently quit once it detects the wrong version to avoid any damage. You’ll also need to jailbreak your device with QuickPWN or the PwnageTool. Lastly, once you have everything setup, you can use Cydia or Installer (from one of the repositories below) to install yellowsn0w, and you’re off to the races!

The iPhone 2.21 OS had gone live mere days before the venerable and always reliable iPhone Dev Team released their iPhone 2.2.1 OS jailbreak solution. The Pwnage Tool jailbreak utility, which has been at the forefront of the iPhone jailbreak scene since its release, is now compatible with the iPhone 2.2.1 OS.

That means Joe iPhoneUser can now update their iPhone or iPhone 3G with a jailbroken version of the new iPhone OS. The iPhone’s baseband firmware lies at the heart of the battle for a viable iPhone 3G software unlock solution. The iPhone Dev Team is working hard to discover an iPhone 3G soft-unlock solution, but be warned - you must update to iPhone 2.2.1 OS using PwnageTool if you ever plan to unlock your iPhone 3G. Of course, if you have and original iPhone, or have a Windows machine, you can easily jailbreak iPhone 2.2 OS using QuickPWN.

iPhone 2.2.1 OS has been released and the iPhone Dev Team has countered with a new PwnageTool release. PwnageTool 2.2.5 is now officially available to jailbreak any iPhone or iPhone 3G.
