Hi Stan52, update from me.
I uninstalled everything (apple mobile, apple update, bonjour, itunes), installed 7.5 - same error
Updated to 7.6 same error.
Also got on phone to apple who were adamant that if i uninstalled everything , set up a new (xp) user account just to install 7.6 it would solve the problem. They also pointed out that if i'd done the updates in the right order (itunes and quicktime then the phone) i wouldn't have the problem.
So i pointed back to them that maybe when i plugged my phone in, itunes should have made sure i did it in the right order or prompted me to which order i should do it manually!
Any how - followed instructions - yep same error.
Tried plugging phone into another PC on 7.5 , no response to the phone beign connected at all, tried installing 7.6 on another PC that's never had it, works fine. Also the delay in putting message up is very long.
Just about to ring support back up again......
