not being heard

agonizing how to fix this-have the iPhone 4 since 4 weeks, after 2 weeks I used the iPod function and now people cannot hear me anymore on the calls, all static, but I can hear them. No pattern her, unplugged the headphones in and out, tried bluetooth, speaker, does not matter, after a couple of minutes I cannot be heard. Reset the phone already. Any thoughts? TX

When you say you did a reset you held the Sleep/Wake and Home button down for a few seconds and if so you need to take it back .
