ultrasn0w Update for iOS 4.3.1 Being Released Tonight

MuscleNerd just sent an update regarding ultrasn0w for current unlockers on iOS 4.3.1. Ultrasn0w has been sent to testers, and the release will be tonight, unless there are hiccups!

This compatibility release will fix the ‘signal bar issue’ on iOS 4.3.1 and other issues.


This is NOT a new unlock, and is only for existing unlockers with the following…

  • iPhone 4 baseband:
    • 01.59.00
  • iPhone 3G/3GS basebands:
    • 04.26.08
    • 05.11.07
    • 05.12.01
    • 05.13.04
    • 06.15.00

Update on Unlocking Basebands: 05.14/05.15/05.16

Regarding the ‘possibility’ of a downgrade from the iPad 06.15.00 baseband, MuscleNerd believes it’s “99% doable, but other things always seem to preempt working on it”. For those with basebands of 05.14/05.15/05.16, the next unlock will have you update to the iPad’s 06.15.00, then downgrade to an unlockable 05.13.04.

This is exciting news for unlockers. Once released, you should see the ultrasn0w update by searching Cydia. Stay tuned!
