Apple recently released iOS 5 beta which has almost 1000 improvements to the iOS but it also blocks the Gevey sim used to unlock iPhone for all networks and which was the only solution to unlock iPhone 4 currently on recent iOS versions.
After this release, the only way to unlock the iPhone 4 are either factory unlocking or else ultrasn0w (if the baseband is compatible)
However, iOS 4.3.4 is expected to be released soon as JailbreakMe 3.0 has probably found a way to break through 4.3.3. Will the firmware of iOS 4.3.4 block Gevey sim on iPhone 4 and others too?
Gevey sim is a SIM interposer tool. It exploits the iOS baseband. However, this can be fixed by Apple via software update anytime. Also, using Gevey SIM is illegal.
So what do you think about it?
gevey sim is working perfectly fine on os 4.3.4 & 4.3.5.
i personally checked it.
on iPhone 4?
