finally got a new macbook pro. i have my iphone 4 synced to an acer netbook. i would love to now sync the iphone to the mac and retire the netbook. i want to sync all my apps and photos from the iphone to the new macbook. when i try to sync the photos it says it will be replaced by the empty photos folder on the mac. how so i sync the iphone w/o wiping out the iphone 4? thanks!
