If you’re shopping around for a new smartphone and tablet, it would be wise to check out your local T-Mobile store (or visit their website) and take a look at the two new gadgets they are selling. First, we have the long awaited T-Mobile G-Slate, manufactured by LG, which we first saw on display at CES 2011. The 8.9 inch tablet runs Android 3.0 and features a 4G radio for use on T-Mobile HSPA+ network. Initial reviews claim the G-Slate has great hardware and build, but the UI isn’t perfectly polished just yet. In any case, the G-Slate can be yours on a two year contract for $529.99. For $750, you can purchase the LG G-Slate off contract. Next, we have the T-Mobile Sidekick 4G, manufactured by Samsung, and this should be a hit with former Sidekick owners as it bears a similar design, but runs the modern Android 2.2 OS. The Sidekick 4G features a 3.5 inch touch screen, slider QWERTY keyboard, 1GHz processor, 3MP camera, and a front facing camera. In addition, it costs only $99 after a $50 MIR on a two year agreement. Considering it has a 4G radio and 1GHz processor, $99 is a good price point for the redesigned Sidekick.
