My wife's iPhone 4 is outside of Apple's 1 year warranty and now the microphone is not working. It'll work for a matter of seconds and then boom -- I cannot hear anything. While this might be a good app for husbands, it's adversely affecting her when she makes calls. She rarely updates her iPhone, so I'm thinking it's hardware. With her iPhone out of warranty, will Apple replace it or offer service? She's up for a full subsidy, but the podcast I listen to recommends waiting for the new iPhone 5. Is this one of those 50/50, be nice and hope for the best type deals?
