I have looked around online a bunch, even went to the apple store for answers on this, and still nothing. I had a MBP, its dead, i got a new one, its awesome. but now i want to sync my iphone with this new computer, I plug the phone in, it all works and everything, but if i click "sync" on any of the check boxes in say, music. apps. rungtones. etc it says it will delete the data on my phone and replace it with the data on that itunes. Is there a way for me to jsut transfer all my **** off the iphone so it syncs with that? this is getting really annoying. The guy in the genius bar told me to backup my phone, then restore it using itunes and that iTunes would then allow me ot sync everyhting without first deleting all the information, tried that, and it didnt work, itunes just said the same message about deleteing all my applications and data and blah blah blah. what do i do! no i dont have the library from the old computer to use as a reference to copy files from.
