With no software unlocks available at higher basebands for Apple iPhone 4, Gevey Sim turns out to be a viable unlock option for those who can’t wait any longer for the iPhone Dev Team to fulfill their promises.
How Gevey Sim Can Help!
Gevey Sim is a really handy tool for unlocking all the higher basebands including 1.59.00, 03:10.01 and 02.10.04 on iDevices that run on iOS 4, 4.1, 4.2, 4.2.1, 4.3 and even iOS 4.3.1 without requiring a jailbreak.
Note: When you try to unlock your iPhone 4 using Gevey Sim, make sure that you’ve sufficient battery to sustain for an hour or two, and you also need to be careful that your iDevice doesn’t get switched off accidentally during the process, otherwise you may lose the unlock!
The GEVEY turbo SIM costs $70, and is definitely a slightly expensive option, but until there’s a software unlock available for higher basebands, it’s surely a good work around.
Well, just like the Gevey Sim, there’s the Unlock iPhone 4 Rebel Sim Card that pretty much does the same job of unlocking iPhone 4 at higher basebands, though it’s not a software unlock again!
So, either wait for the iPhone Dev Team to come out with another unlock for higher basebands, indefinitely, or try out the Gevey/Rebel sim card, and enjoy the flexibility to use any network carrier of your choice.
