Cupcake's on-screen keyboard shown on T-Mobile G1

We already found that the Cupcake branch of Android made available a software keyboard on Nokia's line of Internet Tablets, and now that very functionality is being showcased on a bona fide T-Mobile G1. We can't say how stoked we are to see a real deal on-screen keyboard on the handset, and we're even more jazzed about the eventual release of these caloric goodies to the masses. Have a look yourself at the vid just after the break.
