My confirmation email says "We'll have Specialists ready to transfer your contacts, set up email, and help you get apps so your iPhone is just the way you like it." My 3G is JB and I don't want to virginize before I go in there. I've never bought a phone from the Apple store, so I'm wondering if they'll just let me pay for the phone and walk out, or do I really need to take my 3G with me?
