So I jailbroke my 3GS a while ago on 3.1.2 and then haphazardly upgraded to 3.1.3 without thinking it through. Thankfully, I did not lose any key features such as an unlock, but one strange thing did carry over. I used a little utility from Cydia called "Make It Mine", which lets you customize the title bar on the iPhone. I changed my carrier to "Verizon" just for the hell of it, and it has carried over to my unjailbroken iPhone after about 25 restores. I believe that I have done some clean restores in addition to restores from backups, and neither have fixed the issue. Is anyone aware of a way to change this back to "AT&T" without jailbreaking (since that is impossible for me at this point). Thanks.
