Ok so I jailbroke my iPhone befor the ios4 update and I had downloaded the carrier logo changer. When I updated to ios4 it unjailbroke my phone obviously which is fine because I have a genius bar appt in an hour but the carrier still says my name not AT&T !!! I've restored my phone completely and it's still there! ... I have the program on my computer to go into different files hidden in the iPhone do you think this will work ? If so where would the jailbroken apps be stored?
