I'm actually getting bummed about this. My girlfriend has been getting pissed at me lately, she calls and it just doesn't ring, even when I'm in a perfectly good location with great reception. At first I thought it was an issue of me being on the phone and it not coming up to end call or put the person on hold. But it seems to happen a lot. Very frustrating since we work opposite hours and she calls me on her lunch break and when I dont pick up, eh, whatever the reason, annoying as hell as I never had this issue with other phones on AT&T, I've been with them for over four years now.
