Has been continuously rebooting. I got this about 2 weeks ago, and it has been doing so upon arrival.
I have factory reset it as well.
I was completely satisfied with the Droid X I purchased on release day. A few reboots, and no issues until the charging port stopped working. This one has rebooted atleast 20 times today, and last night it wouldn't not send calls or texts, nor would it recieve them.
