[apparently official] no iphone without contract
check this out!
What to bring.
To purchase and activate iPhone 3G, you need the following:*
Social security number
Valid, government-issued photo ID
Your current wireless account number and password or PIN (if you’re new to AT&T)
Remember to sync your current iPhone one last time before you come into the store.
so apparently no getting out of apple store without activating it or a contract. :(
No contract option coming soon
