Can I buy Iphones at Apple Store or AT&T w/o a contract?

I want to buy a couple as a gift and want to know before I head down to US.

I don't remember but I recall you need to show drivers license and credit card only.

ATT wants you to activate it before leaving. Apple wants a CC only, no activation.
