Samsung Galaxy S Blaze 4G is a mouthful to say, but it's a nice device for T-Mobile. Here's what you need to know. It's got 4G HSPA+ support, of course, and also a 4-inch Super AMOLED screen, a 1.5GHz dual-core processor, and a 5-megapixel camera capable of 720p HD video. There's also a 1.3-megapixel front-facing camera. For more specifics, check out my hands-on take here.
