T-Mobile's Android roster is growing in number and sheer benchmarking virility today with the launch of the LG-produced G2x. This handset runs bone stock Android (Froyo today, Gingerbread in the future) atop a dual-core NVIDIA Tegra 2 system-on-chip, and just like its international twin the Optimus 2X, eschews the physical flair and focuses on being the best damn 4-inch smartphone that it can be. It costs $199.99 on a two-year contract and can be bought online today or in stores starting April 20th. Also scheduled for general availability on that date is the QWERTY slider-equipped Sidekick 4G, though that sleepyhead is missing out on any early web availability -- it's probably too busy adjusting its tricked-out Android skin and checking that its magenta accents are all spotless. Links are below, whether you're feeling inquisitive or acquisitive.
