I didn't do a massive amount while my phone was jailbroken (for the best part of 2 days), but what I did do was change the carrier name. Since I restored my phone using iTunes, the carrier name has not changed and remains what I set it when I jailbroke. I re-jailbroke, downloaded FakeCarrier, and pressed reset, but nothing happened. Does anyone have any suggestions on how to change this all back to normal? thank you.
