Hi there I did some google searches and am still not sure what could be wrong with this Iphone i've acquired. It used to run smoothly on the t mobile network but now there is no service and wi fi does not work either. On top of this the Cydia app and most other apps wont run. The current fw version is 5.0.1. If someone could direct me to the possible problem it would help me zone in on the solution. Much thanks in advance!
