My phone was in the dock and I got a phone call that I didn't answer and let go to voicemail. Right after the voicemail msg was left, my phone went to the boot screen--the one where it sayd "Droid" and then the droid "red eye" appears. I tried taking out the battery, but when it loads it still gets stuck on this screen and it just keep repeating itself.
Mine did the same thing for a good 20 minutes after suddenly rebooting while sending a text message. I left the battery out for... eh, I'm guessing 40 minutes. When I replaced the battery and powered it back on, I was up and going in 30 seconds.
Any luck so far? I wonder if there's a safe mode you can boot into, like on the BB's.
