We'd kinda gotten used to the cold, hard reality of being teased with the promise of a Cupcake build on our retail G1s out in some distant, nondeterministic future that we may or may not be a part of -- but all of a sudden, it looks like we might've vaulted right past Cupcake. We've now received multiple tips this evening suggesting that T-Mobile may have started distributing Android 1.5 as an over-the-air update to G1 owners, which would bring customizable widgets, messaging enhancements, virtual keyboards, and UI tweaks (among many other goodies) to an eager public. Anyone out there seeing this?

P.S. - No, your eyes aren't deceiving you: these are little green pastries baked by T-Mobile. "We heard people wanted cupcakes," one representative told us.
