The other day I had the following interesting situation on my iPhone 5. I wanted to blame it on Sandy (the winds were a-blowin' a tiny bit more than usual). I boarded Airplane Mode and then immediately disembarked, and everything was back to normal. Anyone ever experienced a no-bar situation on the iPhone 5 (or other)? Just curious, as I'm not worried about it and I'm considering it as just a fluke.
