Previously, we told you about the GEVEY SIM hardware unlock solution for iPhone 4S. Other hardware unlock solution providers like TP Sim and R-SIM also released their updated hardware to bring carrier unlock support for iPhone 4S. These hardware unlock solutions worked perfectly with all operators except Verizon and Sprint. The users of these two companies were unable to unlock their iPhone 4S with any hardware solution to use iPhone 4S on GSM network. Now we have good new for Verizon and Sprint iPhone 4S owners that the makers of GEVEY SIM hardware unlock solution have released GEVEY SIM Ultra S which will unlock Verizon and Sprint iPhone 4S.
Remember that two weeks ago a version of GEVEY SIM was released to bring carrier unlock solution for iPhone 4S but the difference between GEVEY SIM Ultra S and the previous version is that the new version support Verizon and Sprint iPhone 4S and older version does’t. This new GEVEY SIM unlock works for both GSM and CDMA iPhone.

In order to user GEVEY SIM Ultra S on your Verizon or Sprint’s iPhone 4S, you need to jailbreak your iPhone 4S. But if you have GSM iPhone 4S then you don’t need to jailbreak you iPhone 4S. GEVEY SIM Ultra S will not support newly released iOS 5.1 firmware as it will also update your iDevice baseband so, stay away from iIS 5.1 firmware. GEVEY SIM Ultra S is available for only 60$ and can be pre-order on GEVEY’s official website.
