Phone wiped itself after battery pull?
Ok, so last night my girlfriend decides to pull the battery on her Curve 8530. Don't know why, I showed her how to reboot her phone without a battery pull. When she put the battery back in, the phone began wiping itself. There was a white screen and it said "Wiping" with a status bar below.
After the phone finished booting, her contacts where gone, she needed to redo all her settings, and all her app icons where moved back to her download folder. The apps were still installed, just the icons where moved. The OS remained the same (5.0.734).
My question is - why did the phone decide to wipe itself, and has this ever happened to anyone else?
