i'm pretty sure this is an OEM feature with the centro. i thought i was immune from this when i first got it until one day i looked over and my phone was rebooting itself for no apparent reason. i dont hotsync often so i havent had issues there, but i have had it reset on me when using the IM program. id say it does it a couple times a week, if not more often. most of the time i wont even notice it.
