T-Mobile added another Android handset to their 4G arsenal today with the release of the Samsung Galaxy S 4G. The successor to last fall’s Vibrant, this phone features nearly identical hardware. Customers get the same 4-inch screen size, 5-megapixel camera, and 1GHz processor as before, but now they also have support for the HSPA+ 4G (21Mbps) network as well as front-facing camera. Oh, and it also has Inception loaded on it instead of Avatar. For many of you existing Android owners, this won’t make you want to change devices. However, those of you looking to graduate from feature phone to smart phone, the Galaxy S 4G is an attractive buy at $199.99 after $50 mail-in rebate. Wanna buy one outright? Pull $499.99 and some tax out of your pocket.
