Ill be moving from a PC to a new imac tomorrow... In the past on a PC when switching computers, even if I register with the same Apple id and Itunes account, upon syncing on the new computer for the first time, the sync will completly wipe the iphone. Is there a way to make this new imac the iphone's sync computer, without having to erase everything? If I do a backup of the phone on the new computer - then sync (erasing everything) setting the imac as the new computer - and then restore the back up to the phone, will that work? Tips/suggestions please. Thanks.
