I have an iPhone 3GS on firmware 3.1.3. It's jailbroken with Spirit. If I want to run T Mobile service on it, what do I have to do? Do I need to update to 4.0? I've heard that I need to take it to the T Mobile store and they do stuff with it to make it run after it's been unlocked. All help is...
I have an iPhone 3GS. My friend also has one and he says he tethers his 3G internet from his phone to his router. How can I do this? Also, both of our iPhones are hacked.
