I finally called pa1mOne to exchange my Unlocked Treo 650. The phone just kept turning itself off.

1. If I lightly bumped the unit (while on my belt clip) again the arm rest (chime) it would turn the phone off.

2. If I resnapped the case (Because pa1mOne designed a Treo 650 case without a slot for the camera to take pictures while securely snapped in the case) it would (chime) turn the phone off.

I would turn the phone back on (entering my SIM password) several times a day. If my sound was off, my phone could be off all day without me knowing it.

They will advance ship the new one for free. Should have it next week.
