I was sitting in a coffee shop last night with my Treo 650 (Sprint model) in a jacket pocket when I heard the tune indicating that the phone had reset.

Note the time, exactly 6pm, which seems suspicious. There are no calls in the call log at that time. The previous call was about 25 minutes earlier. There were no timers, alarms or other events scheduled.

Just wanted to document this in case it means something to anyone. Here's the message from ##ERR

A reset was caused on 1/31/05 at 6:00 pm while running "Phone":
