We knew it was coming, we just didn't think it'd be here so soon. According to T-Mobile's coverage maps, my home, my office, and the rest of the San Francisco Bay Area is now blanketed with 3G data coverage. According to my Sony Ericsson TM506, one of my network options is now "T-Mobile 3G." Sweet.
T-Mobile News has a nifty page up with thumbnails of the coverage maps for 10 of T-Mo's new 3G areas: check it out.
Can't wait for that Android phone launch tomorrow :-)
