Is anyone else getting random 3G upgrades from T-Mobile?

For the past month, I'm randomly finding myself in 3G coverage when I previously did not around the city of Rochester. Anyone else seeing this in other cities?

I know that T-Mobile is about to shock the cell world within the next month by rolling out many more 3G markets and then upgrading everyone to 3G+, making it the fastest 3G network in the country. But this is really nice.
