Engineers out there, please i need you to help me with my iphone/iTunes. iTunes does not see my iphone 4s when i plug it in but windows explorer sees it whenever its been plugged.I first thought its the cable but when i tried plugging it on a friend's laptop using same cable, its works and itunes sees it and gave comprehensive details of the phone. I was told it could possibly be that my itunes version 10.1 is outdated so i updated it online yesterday but still wont work. Please help me cos i need to transfer stuffs to it and backup regularly. Thanks in anticipation.
