This might be simpler than you think. The only device authorized to be sold by Samsung in the U.S. is the P-600. Anyone selling a P-601/5 has imported it and it comes with no warranty from Samsung as it's considered grey market. I have a P-601 I got from Negri and it's from Trinidad. Knowing it has no warranty I insured it through SquareTrade. That's an option for you too if you buy from someone like Expansys, Negri, or NewEgg. You can get SquareTrade on eBay items too if you do it at check-out. But if you're looking for warranty support from Samsung your only choice is buying a P-600 from an authorized Samsung reseller. VZW's releasing their version of the P-605 (LTE) soon but it'll cost you an arm and a leg. If you weren't aware, the imported P-605's don't support the U.S. LTE bands so you'll be stuck using HSPA. And both it and the P-601 work fine on AT&T but only work on T-Mobile in markets they've re-farmed to 1,900MHz. I get about 5-8MB download speeds using my P-601 on AT&T.
