My sister has the Droid Pro as well, and it's suffering from the same reboots described thus far on this thread. The phone will reboot at any time- whether you're in a phone call, text, or app, it doesn't matter. I first suspected a random app being the problem, but after uninstalling every single app, it kept restarting. This is her second DP in ~35 days.
Personally, I wouldn't suggest anyone get this phone due to these errors. Not to mention, Verizon puts you through a hellhole to get a new one.
