We have just received some exclusive screenshots showing iPhone 4 unlocked using Gevey SIM, on 2.10.04 baseband, running on T-Mobile US network.

The Gevey team has announced a new unlocking method for iPhone 4 users who are stuck on iOS 4.2.1, with 2.10.04 or 3.10.01 baseband.

As we all know by now, the exploit which iPhone Dev Team, including MuscleNerd and Sherif Hashim, thought would work to unlock iPhone 4 on 2.10.04, 3.10.01 and 4.10.01 basebands unfortunately turned out to be a no-show in the end.

Good news for iPhone 4 unlockers as we have yet another update, this time from none other than the man who actually works on the Ultrasn0w, MuscleNerd of iPhone Dev Team!

Its been a while since we last heard or read anything on the upcoming iPhone 4 unlock for 3.10.01 and 2.10.04 basebands. MuscleNerd of iPhone Dev-Team has already confirmed that unlock for iPhone 4 on newer basebands wont be released until Apple drops iOS 4.3 to public.

Here is a quick little heads up for those of you who have been waiting for iPhone 4 unlock on 3.10.01 and 2.10.04 basebands. MuscleNerd of iPhone Dev-Team has confirmed now that no unlock will be released until iOS 4.3 / 4.2.5 (whichever is last) is public.

Great news for iPhone unlockers! It seems like Sherif Hashim has managed to crash the new 05.14.02 and 2.10.04 baseband which can ultimately lead to an unlock for iOS 4.1 and iOS 4.2 for both iPhone 3GS and iPhone 4 users.

The final version of iOS 4.1 features a new baseband 2.10.4 which is currently not supported by Ultrasn0w 1.1-1. If you update your iPhone 4 to iOS 4.1, and then later downgrade back to iOS 4.0.x (with SHSH blobs), you still wont be able to unlock your phone as the downgrading of firmware wont downgrade your baseband, hence making it impossible to unlock.
