Today I have some good news. If you are Verizon and Sprint iPhone 4S user then this news is just for you. There came new update fro Gevey Dev team. They have recently released Gevey Ultra S to unlock GSM and CDMA iPhone 4S. It was designed to unlock iPhone 4s running iOS 5, 5.0.1 and 5.1. Some say that there is not need to jailbreak iPhone but I recommend you to do this because this SIM uses furiosmod to unlock devices.

unlock CDMA iphone 4S

As you see you can unlock only iPhone 4S on iOS 5 and iOS 5.0.1 because there is no jailbreak for iOS 5.1 yet. But if you have already updated your iPhone 4S to iOS 5.1, don't worry, you can simply use this link to downgrade iOS 5.1 to 5.0 or 5.0.1. And then jailbreak it. Update: If you are waiting for free unlock you can use this link to find out more about iPhone 4S free unlocking method by pod2g.

Geve Ultra S can unlock GSM and CDMA iPhone 4S

Gevey Ultra S is CDMA Interposer Sim  that can unlock iPhone 4S using CDMA and GSM networks on Verizon and Sprint carries. Also there are some others methods that can unlock 4S. You can use such Inter-poser sims as TP-Sim and R-Sim 3 unlocking solution but there is one thing, they both don't work with Sprint handsets. So if you are Verizon or Sprint users this Sim card unlock is just for you. So don't waist your time and order it. Note: Do not update your phone to iOS 5.1 till jailbreak will be available.
