Anybody have any issues when on the phone to somebody else? i can hear who i'm speaking to fine but the person on the other end of the line can barely hear me. Anybody else have issues with that? Iphone 4 is a great piece of kit but want to know if anybody else has a problem like this or can the other person hear you great? overall what do you think of the sound quailty of the phone compared to the 3G and 3gs?
