Sn0wbreeze 2.9.4 allows users to create custom iOS 5.1.1 firmware file that is pre-jailbroken, which can then be used to upgrade their iPhone, iPad or iPod Touch to iOS 5.1.1. In case of iPhone, Sn0wbreeze also preserves the baseband from getting upgraded so that it can be unlocked using Ultrasn0w (though Ultrasn0w is not yet compatible with iOS 5.1.1).
Sn0wbreeze 2.9.4 supports the following iOS devices running on iOS 5.1.1:
- iPhone 3GS, iPhone 4 (GSM)
- iPad 1
- iPod Touch 3G, iPod Touch 4G
- Apple TV 2
