1.1.1 Jailbreak Problems HELP!
so i had an unlocked 1.1.2 and tried to upgrade to 1.1.3 but i downloaded the wrong file which was Official 1.1.3 upgrade. So i downgraded to 1.1.1 and then did all the necessary steps to get to 1.1.2. Then i unlocked on 1.1.2 using 1.2.u or something like that. It seemed everything worked fine until i realized that i could not receive or send calls. Everything else on the phone worked fine no error message or anything just the calling problem. So i downgraded again to 1.1.1 but now the *#307# does not work. How can i get back to a unlocked 1.1.2? thanks
