From the makers of PwnageTool and QuickPwn, the Dev-Team has released version 0.9.1 of their Yellowsn0w application which promises a genuine iPhone unlock for any iPhone up to firmware v2.2.
While tools like QuickPwn and PwnageTool lift the restrictions of the iTunes App Store, Yellowsn0w allows the iPhone to operate on any network that uses the UMTS/HSDPA 850/1900/2100 frequencies of the popular Apple mobile.
The hacking lads outline the basics of the tool in their release:
- The unlock works exclusively with baseband 02.28.00. This baseband is provided by the latest firmware update (2.2) from Apple. You’ll need to upgrade to this release using iTunes and then use QuickPwn to activate etc. There are plenty of tutorials about this on iclarified, bigboss, and other established tutorial sites. Because it works on 02.28.00, it is available to everyone on the planet. This means we don’t need to unnecessarily expose holes in earlier basebands, which is an important concern.
- The application is a small daemon that is launched on boot. It injects the payload at boot and also whenever there is a baseband reset. You won’t notice anything about it other than that your third-party sim now works. It’s a small program and unobtrusive. There is no GUI (this is by design).
- You can add the application using the sources outlined below (coming soon). There are Cydia and Installer sources available, so use whichever you are comfortable using.
- yellowsn0w is completely removable through Cydia, the command line, and iTunes.
The large variety of networks and SIM cards this tool will bring the iPhone to in coming days is sure to reveal bugs within the application. For users who don’t experience success on day one, the Dev-Team cautions patience.
