Sprint is first to market with a US version of the Samsung Galaxy S II, and it's a winner. They've increased the display a bit to a pocket stretching 4.5", and it's still that super-rich Super AMOLED Plus technology. The phone has a dual core 1.2 GHz Samsung Exynos CPU with GPU, and it's by far the fastest mobile CPU in a shipping phone. The smartphone runs Android OS 2.3.4 with Samsung TouchWiz software, and it has 16 gigs of internal storage along with WiFi, Bluetooth and a GPS. The phone has 4G WiMAX and 3G on Sprint's network, and a beefy battery to combat the drain.
