T-Mobile’s first 42mbps capable phone is now available for purchase nationwide. Although their 42mbps HSPA+ network isn’t ready yet, users can still enjoy the 21mbps download speeds on their current 4G network. The Samsung Galaxy S 4G also comes with a front facing camera for video calling purposes, and comes preloaded with last year’s summer hit blockbuster, Inception. Other than that, the Samsung Galaxy S 4G has pretty much the same specs as the Vibrant – 1GHz processor, 4″ display, Android 2.2, 5 megapixel rear camera, WiFi, GPS and Bluetooth. The Galaxy S 4G can now be yours for $199.99 after a $50 rebate with a 2-year contract.
