I have a MacBook with Leopard on it and I want to do a fresh install of Snow Leopard. I will be able to manually transfer all my files to an external hardrive and back except for iTunes. I have 2 iPhones and 1 iPod Touch that syncs with my iTunes. If I just copy the iTunes folder will my phones and iPod touch still sync with iTunes or will I have to wipe + resync them? Thanks for your help.
