Hi I got my iphone 4 today and for some reason my mic doesnt work on facetime or video recording. For everything else it works perfectly like Phone, Voice memo, IamTpain etc..... I called the apple store but they told me that it is a problem with my wireless. I tried facetime from my house, my girls house and starbucks and I got the same issue. And also the mic for the video recording does not work even when shouting into the mic. I performed a restore and again same issue. If anyone is having this same issue please let me noe if youve figured out a fix. Thank you
