I've been contemplating buying a Droid X for a while now, especially after reading all the rave reviews and was seriously about to take the plunge. However, lately I've read more than a few complaints about the phone freezing up since the 2.2 Android upgrade, and other issues such as the unit shutting down spontaneously. These negative aspects concern me. So my question is: Have any of you been experiencing issues with constant freezing or shut-downs???? Does this have to do with the upgrade? I'm wondering if I go out and buy this phone tomorrow, I might have the same problems. Any thoughts?
