This morning my phone froze up on me while using an app. I pulled the battery only to have the phone get stuck in the start up process. It would circle around from the HTC to the DROID screen then back. I couldn't get past the DROID screen. So I preformed a factory rest. Now it is receiving no signal, so I can't reactivate the phone. I have no other line to call tech support, and my local store is an hour away. Has anyone heard of this, or have tips on how I can fix it?
