So I was on AT&T with my old iPhone and my boyfriend got me a new 3GS from his friend and he got my old phone, along with a new t-mobile plan for us. We're trying to unlock both phones and it all seems successful, but there's no bars in the corner of my 3GS. It doesn't say no service, just empty bars. It doesn't say tmobile next to those either. Cydia is there. No sim service, but wifi works. What's weird though is the network tab in settings. The screen freezes and I have to hit the home button to unfreeze it. I'm using pwnagetool and iTunes wont let me option-restore back to 3.1.2. what should I do? The 3GS was jailbroken from our friend and he stored the shsh hashes or wahtever so does that help? Hopefully I made this understandable. Please Register or Log in to view images thank you!!
