We already reviewed the Sprint version, we’re working on reviewing the AT&T version, and now we’ve gotten our hands on the T-Mobile version. Samsung’s Galaxy S II is the fastest-selling smartphone the South Korea-based electronics giant has ever made, and for a good reason: this is a beast of a handset. The dual-core 1.5GHz Qualcomm Snapdragon processor screams, the HSPA+ 4G flies, and it goes without saying that Samsung’s giant 4.52-inch Super AMOLED Plus display is nothing short of amazing. No display even approaches Samsung’s latest panels when it comes to combining unbelievably rich colors, brightness and remarkable clarity. But with new phones on the horizon for the holidays and Google’s next Nexus set to be unveiled in the near future, is T-Mobile’s Galaxy S II worthy of a 2-year commitment? You’ll have to wait for our full review to find out, but in the meantime be sure to check out our hands-on photo gallery below.
