QuickPwn

In just a few short days the iPhone Dev-Team has worked out a fix for users interested in upgrading to 2.2.1 firmware without breaking the yellowsn0w unlock. As was announced earlier this week, the new firmware update from Apple changes the baseband version from 02.28.00 to 02.30.03, rendering yellowsn0w impotent.

If your device is an iPhone 3G and you're interested in unlocking now or in the future, you must follow the Dev-Team's Golden Rule. First and foremost do not use the iTunes update process without using PwnageTool. This means the official ipsw file for 2.2.1 must be modified so that the older baseband is preserved. Furthermore, the Dev-Team says this cannot be done with QuickPwn.

PwnageTool 2.0.3 for Mac OS X is now available from the iPhone DevTeam. According to their blog, this new version supports iPhone and iPod firmware 2.0.2 5C1. The latest version updates Installer.app to beta 6 and also contains a localization for Germany.

Along with the latest Pwnage tool for Mac, the iPhone DevTeam has also released the ‘150’ beta update to the Windows QuickPwn application. This update improves the user interface, provides bug fixes for YouTube, and the adds BootNeuter support for unlocking 2G iPhones.
