Aaron unboxes the Samsung Galaxy S 4G, the newest member of the Galaxy S line and a device that's coming to T-Mobile on February 23rd for $199.99.  It's more of an evolutionary upgrade to the Samsung Vibrant, with Android 2.2 (Froyo), bigger battery, front-facing camera, a few new apps, and a new battery cover.  Other specs include a 1 GHz Hummingbird processor, 4-inch Super AMOLED display, and 5-megapixel camera.  A particularly interesting feature is the DriveSafe app, which allows the Galaxy S 4G to send an automatically generated text message while you're driving.
