Hi guys, can any one help me with my iPhone. I have an iPhone 4 and it is currently running on iOS 4.3.4. I have managed to jailbreak it using Redsn0w. Right now, what I want to do is unlock my iPhone. Can I use Gevey SIM to unlock my iPhone 4 on iOS 4.3.4 firmware?

Well, for those of you who aren’t aware, Gevey SIM is a special SIM interposer that has capability to unlock iPhone 4 running on iOS 4.1 up to iOS 5 beta 2. Unlike Ultrasn0w carrier unlocking tool, Gevey SIM is hardware unlock which works on all version f iPhone baseband. With Gevey SIM, you can unlock iPhone 4 with baseband 01.59.00, 02.10.04, and 03.10.01 (basebands not supported by Ultrasn0w). Additionally, with Gevey SIM you don’t have to jailbreak your iPhone in order to unlock it from its official mobile phone carrier. But, we at Jaxov highly recommend to jailbreak your iPhone first before unlocking it with Gevey SIM to ensure that all features of the iOS works smoothly on the unlocked iPhone.
