It's a fantastic way to get people to buy the T-Mobile version (well I don't know how much data I use, but maybe it's under 200MB/mo) and then upsell them to a plan after 4 YouTube videos.
Plus you can pull this out of your advertising budget, and the marginal cost of the infrastructure use is pretty much zero, at least until T-Mobile's subscriber numbers go up rather substantially.
