Apple has released a new minor iOS 5.1.1 update for iDevices
including iPhone 3GS, iPhone 4, iPhone 4S, iPad, iPad 2, iPad 3, and iPod
touch. There is not any new feature in the update, despite some security fixes
that were found in the iOS 5.1, but the most important thing about the new
update is that the iPhone 4S running on iOS 5.1.1 can unlock now using the
Gevey Ultra S SIM unlock or R-SIM unlock. Actually Gevey Ultra S SIM unlock or
R-SIM unlock is a hardware unlocking solution that can easily unlock the iOS
powered devices easily.
To unlock your iPhone 4S using Gevey Ultra S SIM, it must be
running on iOS 5.1.1 on following basebands, otherwise it won’t work properly.
- 1.0.11
- 1.0.13
- 1.0.14
- 2.0.10
- 2.0.12
Note: The Gevey Ultra S unlocking solution is only compatible
with iPhone 4S, to unlock iPhone 4 you have to buy specific unlocking solution
for iPhone 4 which works with all basebands except 4.11.08 and 4.12.01.
