It also had a random error message telling me my accessory wasnt optimised for this iPhone although ihad no accessory :| Anyways i went to the genius bar and after half a ton of dust was cleared out of every possible oriface he agreed it should be replaced with one of their reconditioned ones. Happy days I restored it from my orihinal back up bar my apps so only had contacts messages photos etc etc.. Its been a week and i was gutted when i noticed the missus shouting hellooo?? Down the phone at me when she couldnt hear me and yup she started crackling. Suppose its another 50 mile drive to my Apple store to get another one?? :/ just for it to f**k up again? Or any better ideas?
