My first TBolt was rebooting itself a couple times a day, so I exchanged it at Verizon and only a few hours after getting everything set back up on my new one, it too rebooted on me. I then remembered one of the settings I had enabled in my ADW Launcher - "System persistent" - disabled that and haven't had a reboot in almost 3 days since. I have noticed that with that option disabled the launcher reloads a lot, which would explain why it was causing the phone to reboot. I am happy that I exchanged the first TBolt though, because I didn't realize how quiet the sounds were on my first one until I got my replacement, I thought that's just the way that phone was and I'm relieved to find out it's not. Fast boot never worked for me on the first phone either and this one works perfectly.
