There have been a whole bunch of false starts on this, but honestly, folks -- for real, we're not messing around -- T-Mobile has finally started distributing Android 1.5 over-the-air to American G1 owners. This means that anyone who hasn't taken the time to install the update of their own accord is just about to get hooked up without any intervention whatsoever, bringing third-party widget support, a virtual keyboard, email and messaging improvements, a revised UI, and of course, an endless font of delicious pastries that will make you morbidly obese if you eat enough of them over time. Honestly, while you're waiting for the update to arrive, hop on the Bowflex for a few minutes. It's not going to kill you.
