Some get them some don't. An app that is incompatible with 3.3.4 maybe or defective hardware. I've had one random reboot since release day and I was browsing the web, texting, listening to a song, and downloading something from the web all at once.
I couldn't blame it for that. None since. Do you leave WiFi on? I read somewhere that a user thought it had something to do with WiFi.
Mine has been doing it once or twice a day since I got it (2-3 weeks ago) and I NEVER have wifi on unless I'm out and about (20% of the time), so I doubt wifi is the culprit.
