I activated my phone last night, things went smooth and quick. Used Siri for texting and it worked well...didn't make any phone calls though. Now I have been in a no AT&T area today so I didn't get to make any phone calls...make one tonight and my wife can't hear me. Ok, I had the aux wire in the car plugged in, maybe it didn't recognize it's removal. Nope! Tried headset, nothing. Regular phone, nothing. Speaker phone has lots of background noise. Going to backup the phone, try a restore and see if that works. Otherwise, making a Genius Bar appt for tomorrow when I get home.
