It amazing the GPP still works on IOS 6.1.3 newly released yesterday by Apple. The GPP unlocks any iPhone 4S from any carrier worldwide, including Sprint and Verizon USA! If you have bought one from us and want to update, please contact us for a proper course of action. Thanks

From what we have heard, 6.1.3 has patched the exploits used to jailbreak so stay far away from this update please. As for GPP unlockers we have not received confirmation it works yet with 6.1.3; but we're optimistic a software patch will be updated to support it soon.

This is what the T-Mobile mms and other companies settings should look like and where to type them in to your iPhone.

Here's a darn good one, as we have seen some customers fooled already coming into our shop believing they had an iPhone that needed repair :p
