While T-Mobile remains quiet on the official release of the T-Mobile G-Slate, the first Honeycomb Tablet to grace the Magenta network, retail stores across the land are seeing demo units arrive along with accessories. Combined with last nights indication that three “iconic” devices are releasing on April 20th all signs point to the G-Slate joining the T-Mobile G2X and Sidekick 4G on that magical day.

We’ve had plenty of hands on time with the T-Mobile G-Slate and you can see our hands on video at CTIA last month.

P.S. Check out the pair of the red/blue 3D glasses included in the box!
