Is it possible to upgrade to 1.1.3 from my jailbroken 1.1.2 without bricking my phone? All I want to do is upgrade and not jailbreak it. I just want the regular upgrade but I previously jailbroke my phone on 1.1.2 and now I want it back to normal. Is this possible without bricking my phone? If this doesn't make sense tell me and I'll try to make it make sense and Thanks in advance for any help!!!
