This afternoon, all of the features on the external screen of my Moto Droid seem to be frozen. I can't unlock the phone, and none of the Back, Home, etc keys are working either. I took it in to a Verizon store, and the employees all claimed it was an issue due to the most recent upgrade. Anyone else having this issue? And if so, has anyone been able to fix it? Verizon's solution was to send my a refurbished phone (which I'm not at all happy with). Please advise. Thanks!
