  • Will Jailbreaking my iPhone 3GS ruin my unlock? I have an AT&T iPhone 3GS on 6.1.3 (I know there's no jailbreak for it yet, but I know an untethered is being made) and I have it unlocked to be used with T-Mobile. If a untethered jailbreak comes out for 6.1.3, will my unlock be ruined and not let me use my T-Mobile services? ps. I have it unlocked, not jailbroken, so I don't have cydia
  • Will jailbreaking iPhone unlock it? I have a black sprint iPhone 4S, and I have t-mobile. IPhone 4S's come with a sim card holder and tray too, but I have to go to sprint directly to unlock it for a high fee. I heard if I jailbreak it, it gets unlocked and I can use t-mobile with it! Is this true? Will jailbreak unlock an iPhone 4s to use any carrier, and if so how do I do it?!
