I just got an ulocked treo650 it says cingular on it but i use my tmobile gsm chip in it.
everything is working great except after trying to get the phone to turn on after a night of sleeping it will not turn on.

the blinking green light is there but the screen will not turn on when i push the power button (red hang up call button).

none of the buttons will turn on the screen.

I have to soft reset the phone to get it to turn on, not even taking the battery out and back in will turn it on.

Anyone have any idea what could cause this.

the phone turns on fine thru out the day it is only in the morning when it has been on standby for several hours.

I have no idea what is going on.

Thanks.
