Oh those silly online resellers. MobileCity has just put up a holding page for the T-Mobile G-Slate with a price of $699.99. Of course this price is subject to change and this is just a placeholder so it’s possible this could disappear entirely and reappear with a price higher or lower so you can’t say you haven’t been warned. If you needed a reason to break open the piggybank for 3D tablet goodness, I’d say now is the time. Still no official word from T-Mobile as to when we can expect an official launch, however our intel places this device on store shelves right around March 23rd.
