Yesterday after I installed "setting profiles", stock and some new apps and then I left my N1 on and went to sleep. I woke up and found my N1 was switched off becuase run out of battery. I turned it on and found that my profile get reset and it just act like a new phone.

All my apps (not from n1 built-in apps) were crash. Some of them even get lost, such as Dolphin HD. I uninstalled some apps and reinstall it and they start working again.

Do anyone give me any direction what I should do? I didn't root the phone.
