[Scrotum]

I have had my Treo Pro for about two months now, and in the last few days I have been experiencing random shut downs. It started on the 3rd of this month, but I am not sure why. Since I live in a very hot area I make sure to keep my phone cool, and never leave it in a place that is not air conditioned, and the only change I can remember is changing out the battery since the one I normally used died after I forgot to charge it for awhile. Anyone else experience the phone randomly turning off?
