I don't know what to call it but my Droid shut down when it ran out of battery and when I started it back again it started off with the typing tutorial and all my contacts were gone, several apps were missing (but not all), Facebook and other accounts were unlinked and all browser history, cookies, bookmarks, and the such were erased. Many apps which are still on the phone now force close whenever I try to start them and other programs (even the Market) have restarted like it was the first time opening, it asks me to accept its terms and conditions. The weird thing is that my calendar, email account, and text messages were all intact. This is very weird, any ideas of what went on? Should I be concerned that this will occur again?
