First, my original Droid has been replaced. This new one has been a dream. Eveything has been working perfectly this morning, until 6:51. I received my morning messages (as usual), and some of them were duplicates, but that is no big deal and that happens from time to time with any network, but the thing that really bugs me is that my PHONE IS NOT WORKING. I can not make a call. Period. I can web browse, I can Facebook, I can message, but I can't call... Not from my numeric keypad or from my list of contacts or from my favorites. Is anyone else having this issue? I have restarted the phone several times. Removed the battery and the SD card several times - and still nothing. I've virus scanned. All clear. I've shut down all applications, unnecessarily, since I had 109 mb free. I can't call Tech Support yet, since I will need a landline phone, but I have sent them an e-mail, ironically, from my Droid. Does anyone have any ideas? Thanks in advance.
