If you want to figure out why your Treo reset itself, when it comes back up, go to the phone application and dial #*377 and hit [Send]. You’ll get a rough idea of what app it crashed in.
(What’s 377? How can one remember it? It spells ERR [as in ERRor] on the phone keypad)
Great tip. I LOVE my Treo 600 (just got it). It has crashed a couple of times and it is good that I am able to find out why. Thanks for the tip. How did you find that out?
