The second major tablet running Android 3.0 is expected to drop on April 20. Of course, I am referring to the LG G-Slate, which will launch much to the excitement of T-Mobile customers and individuals looking to pick up a hot new tablet with T-Mobile. While T-Mobile hasn’t officially announced the release date of the G-Slate, TmoNews has received a picture of an internal T-Mobile Document which announces the April 20 launch date. April 20 is already shaping up to be quite the memorable day as the T-Mobile G2X and the Sidekick 4G are also going to launch. When you throw in the LG G-Slate, April 20th turns out to be quite the winning day for T-Mobile customers.
