iPhone 4 / 3GS Unlock on iOS 5.1 With Ultrasn0w 1.2.6 Coming Soon


iPhone Dev-Team will release an update to its iPhone unlock software Ultrasnow to unlock iPhone 4 / 3GS running iOS 5.1. This is a good news for some iPhone users relying on the iPhone unlock,  the wait will be over.




If you use ultrasn0w for your carrier unlock, be sure to use a custom IPSW to get to 5.1 first!  Don’t ever restore to a stock Apple IPSW!  Use redsn0w’s “Custom IPSW” button to create a NO_BB_* version of the 5.1 IPSW and restore to that instead of the stock one.  (That option is available only to 3GS and iPhone4-GSM owners.)  ultrasn0w itself will be updated for 5.1 in the next few days (same baseband support, not 5.1’s baseband).

Ultrasn0w 1.2.6 Unlock for iPhone 4 / 3GS unlock on 5.1 Compatible with the basebands:
  • 01.59.00
  • 04.26.08
  • 05.11.07
  • 05.12.01
  • 05.13.04
  • 06.15.00

Unfortunely, it seems like iPhone 4 baseband 4.11.08 will not be unlocked with the Ultrasn0w 1.2.6. A new version of Redsnow was released by the Dev-team to jailbreak the iPhone, iPod touch and iPad A4 devices running on iOS 5.1
