My husband has an iPhone 3GS and it is currently synced to an old Mac. He can no longer update his phone op software because his Mac is too old. I want to sync his phone to my Windows computer running windows 7 so I can update his phone. Can I do this without copying the 8 gb of music onto my computer? I am sure once I do this, he won't be able to sync with his old Mac any longer. I read about changing the I'd files but I am not sure this would work in this case. Any suggestions? I know once he gets the phone updated, he won't really need to actually plug into a computer cease he can back up to the cloud. I just don't want to erase all of his music and photos.
