My Sprint Pre is going through a sort of signal cycle. Starting with full bars, the signal goes continually down, to the point where the top bar reads "Phone offline." WiFi work great, and 3G is on and off randomly. I have doctored the phone 3 times, (Verizon 2.0, 2.1, and the original meta.) The problem still persists, and the only way I could log in to my profile was to do the ##DEVMODE# and install the firstuse patch. Is it possible that my antenna is fried?
