[B][FONT=Arial]ULTRASNOW Fix Unlock iPhone iOS 6.0.1[/FONT][/B]

This is not the official ultrasn0w tool that the iPhone Dev Team created. It’s a package that works with the official tool for supported basebands, those that can be unlocked by the official tool itself. This tool can be used until the official ultrasn0w is updated to unlock iOS 6.1
iOS 6 Basebands compatible with ultrasn0w fixer 6.1
Baseband 01.59.00 (iPhone 4)
Baseband 04.26.08 (iPhone 3GS)
Baseband 05.11.07 (iPhone 3GS)
Baseband 05.13.01 (iPhone 3GS)
Baseband 05.12.01 (iPhone 3GS)
Ultrasn0w supports only older basebands, if you want to preserve your iOS 6.1 baseband you need to use custom firmware with redsn0w 0.9.15b3 -- read more here.
