I'm fuming. I went to put my SIM card in my Treo 600 and when I went to turn on the phone connection the phone shut down and refused to turn back on. I put it on the charger and it powered back on, but it reset to the factory settings! I LOST EVERYTHING! I lost my schedule, my extensive address book, pictures, text messages, etc. Now, when I take it off the charger, it resets all over again. It refuses to stay on when off the charger. It was fine yesterday.
