Sound drops out during call - can't hear caller but they can hear me
I've been unable to find this in any thread searches...
The last several calls I've gotten from my wife the sound has dropped out - in the middle of a discussion, no warning, just suddenly I can no longer hear her. She can hear me talking but my sound is gone. This only happens when she's on her cell (another AT&T phone) not on a land line. It's been happening off and on for several weeks - just got worse today with ALL calls (5 or 6) to her dropping out at some point.
I'm on a 1st Gen iPhone with version 3.1.2 (7D11)
Any help would be appreciated.
