hi guys got an iphone, 1.1.4 jail broken only (im on orig o2 contract) today when i tried to call home, i put it on loudspeaker, full volume, i could hear them fine but they couldn't hear me very good at all. loudspeaker off and talking normally worked perfect so im thinking is this a bug with firmware or my iphone faulty? anyone else experiencing same issues? my battery was at 20% level (red), if that makes any difference? any help, much appreciated thanks!
