Hi I have an iPhone 4s CDMA with a Gevey ultra S and after I unlocked the phone, it worked on T-mobile for bout 6 hours then it gave me a "sim faliure", then i took out the sim and put it back in and it shows "No Service", when i take out the sim the phone doesnt indicate "No SIM", instead it stays on "No Service", after multiple tries of turning off and removing/putting back in the sim the phone worked on T-mobile again for another 6 hours then the same problem recurred and im having trouble making it work again. I am running on iOS 5.1.1 can anyone help me with this problem?
