Motorola Droid Razr :: Its Just Factory Data Reset?

For some reason, my phone just did a factory reset. I wasn't using it, just had it in my pocket with headset plugged in. Pulled out the headset from the jack and was going to make a call. When the screen turned on there was the Android icon with what looked like a green "electron cloud" type symbol animated in its open "belly". After a few minutes with that on the display, tried to shut the phone off, it wouldn't power down so I did the volume down and power button. When it came back, the phone was cleared asking me to select a language.
