How to Unlock iOS 5 on iPhone 4,3GS,3G Using Gevey SIM Tutorial Walkthrough

We just have reported you that iOS 5 Unlocking has been released by MuscleNerd using UltraSnow and Procedure has been posted here for following basebands.

  • iPhone 4 – Baseband 01.59.00
  • iPhone 3G,3GS  – Baseband 04.26.08, 05.11.07, 05.12.01, 05.13.04 and 06.15.00

However, if you have been upgraded to higher basebands which are not supported in UltraSnow 1.2.4 then the other alternate for unlocking is Gevey SIM. After unlocking iOS 5 Beta 7, It has been confirmed that iOS 5 unlocking is also working on GEVEY SIM. You must be already aware that iPhone Dev Team including MuscleNerd and Sherif Hashim didn’t turn out to be successful yet in unlocking of  2.10.04/3.10.01/4.10.01 Basebands. However, they still though that they could possibly unlock these iOS for permanent.
