The latest version of UltraSn0w has made its way to Cydia, and it
supports the latest publicly available iPhone firmware — iOS 5.0.1.
You will still need an unlockable baseband to utilize ultrasn0w, but if
you meet the requirements, it is now possible to unlock your iPhone 4 or
iPhone 3GS running iOS 5.0.1…
You will need a jailbroken device to utilize UltraSn0w 1.2.5. Your baseband must also meet the following requirements:
iPhone 4: baseband 01.59.00
iPhone 3G/3GS: basebands 04.26.08 05.11.07 05.12.01 05.13.04 and 06.15.00
This version of UltraSn0w doesn’t bring any new baseband compatibility
to the table, and it only works with the iPhone 4 and 3G/3GS. No iPhone
4S support just yet, but there are rumblings that support could be
coming for those devices in the future.
