T-Mobile's on the move again, tonight expanding their 4G portfolio with the Galaxy S Blaze 4G. Moreover, they've confirmed the 1/11 retail availability date of the 4G-capable Nokia Lumia 710. The Samsung Galaxy S Blaze 4G will be the third smartphone to take advantage of 4G HSPA+ 42 technology running on America's Largest 4G Network. Featuring a Qualcomm Snapdragon S3 processor with 1.5 GHz dual CPUs, a brilliant Super AMOLED touch screen and a variety of pre-loaded entertainment, the Galaxy S Blaze 4G provides fast access to the things consumers want most. The Samsung Galaxy S Blaze 4G is expected to be available later this year. Additional details will be revealed closer to availability, which sadly means that that we haven't been told a price, but we're expecting a mid-range price to create quite the value proposition.
