I bought my Droid last week and yesterday it just started to restart on it is own. I did finally determine that it was rebooting every time I got a notification from gmail. If I went in to gmail on my pc and marked the message as read and then on the next power up cycle my phone would be fine, but as soon as I received another gmail notification, it started all over. It seemed to start within minutes of installing vizBattery widget. I removed it immediately but it didn't stop the restarts, so I began removing all the other widgets and apps that I had installed but it continued to restart. After a few hours of tinkering, I just determined it was better to do a factory reset and went back through and re-installed the widgets and apps (excluding vizBattery Widget) and it is running perfectly.
