I was using my phone last night, no problems, everything was working fine. I woke up this morning and one of the buttons would respond to my touch. Not the lock button, not the power on/off, not the camera button, not the keypad etc... I have taken the battery out several times, thwacked it (as told by crackberry forums), and hooked it up even to my computer. Nothing is working, am i doing something wrong or should i just call into verizon at this point? Please help.
