Amazon puts Samsung Galaxy S III up for US pre-orders, offers a slice of quad-core, unlocked utopia

Sufficiently enamored with Samsung's Galaxy S III that you've got to have one in the US before anyone else, and you don't want it sullied by carrier customizations in the trip across the Pacific? Amazon has your back with pre-orders for 16GB versions in both Marble White and Pebble Blue. Either will keep the speedy Exynos 4 Quad and will stay unlocked, so you can hop networks to your heart's content. Do expect to pay a steep premium for being the first kid on your block: at $800, you're spending a lot to get an HSPA+ model on June 1st when the LTE-toting, cheaper (if carrier-locked and possibly part-swapped) editions should reach the US days later.
