I have an iPhone 4, 01.59.00, that has a mic issue. The caller doesn't hear me. The problem is intermittent, and when it happens I can generally tap (ie: HIT) the bottom, and it will come back to working... sometimes a tap works, other times I have to beat the hell out of it.... Anyway, I've tried to replace the dock connector, with the mic and speaker - but that didn't seem to fix it.
Because this is a 01.59.00, I don't want to exchange or anything... I would like to find a solution. Any guidance would be appreciated.
