Looks like I'll be switching over to an Iphone on Friday. Just to confirm I have to purchase music through Itunes in order to store it on the icloud right? I'm also gonna be grabbing that 32gb Mophie Space Pack. Anyone had any experiences (good or bad) with them and can let me know if they are reliable would be appreciated. I want to get that Lunatik case but they want damn near 120 for them shyts.
