Had the phone working perfectly with ziphone but then got new computer and when I downloaded itunes it messed up iphone. I have tried to use the ziphone software but I can not get the logo and cable screen to move. I have since re-loaded an older version of itunes (7.20) but it won't recognise the iphone when I hook it up to computer. I have tried to hold the power/home button for 7 seconds, let power go and then home but it doesn't work. Anyone any ideas?
