Hey guys, I have an iPhone 4s from Att. I unlocked it for T-mobile using the Gevey Ultra S. Its a simple plug in and play unlock. Although what Ive noticed is, sometime during the day its gonna give me a message that says "sim failiure" a few hours later its up and running again. Im not sure if Im the only one and yes ive tried troubleshooting it. Restored network settings, popped my sim out put it back in and still no luck. Any help would be appreciated THANKS!!
