Today MetroPCS has refreshed their Samsung Galaxy Admire, adding 4G LTE, a better screen, more processor power, and a bigger battery. It features a 3.65-inch TFT display, 1GHz CPU, and a 3MP camera. For $169 without a contract, though, that’s not too shabby. It does come preloaded with Android 2.3, which is likely to be a deal breaker for some. MetroPCS offers a service called joyn that supposedly integrates all of your mobile communications in one place, which is a neat idea. If you’re interested, hit the break for the press release.
