Samsung Infuse 4G
AT&T introduced the world to a 4.5 inch near-beast. With a different processor here and more RAM there, this could have been their Galaxy S II. Instead, it's closer to a Galaxy S phone than anything. It has a beefier 1.2GHz single-core Hummingbird inside, though, which makes it marginally better than other Galaxy S phones.
Aside from its large Super AMOLED display, there are 16 gigabytes of storage inside, 512MB of RAM, an 8 megapixel camera with HD video recording and a lot more. It's not a bad phone to consider if you're a fan of this size. The Infuse 4G has been available since May 15th, 2011.
