I see where folks with other Droid phones have had this issue, but it was a new one for me today. It's not uncommon for my cell phone not to ring all day because I work at home, and most people call my land line. But I picked it up earlier and noticed it said No Service. Yes, my service stinks at home, but I've never seen THAT! I took it outside to try to get a signal and couldn't. I attempted to make a call anyway and it said I was in Airplane Mode. Tried repeatedly to turn it off in Settings. I'd uncheck it, go to the Home screen, go right back to Settings, and it would be checked again. Finally had to turn the phone OFF and then turn it back ON. That worked this time, but I dread having another "issue" with this two-week-old phone.
