Just noticed T-Mo is now offering TV service in some areas, via STBs connected to your home wifi. They recommend at least 50Mbps internet service.

$90/month for T-Mo customers, + tax. 400 hours HD DVR storage, with an individual DVR, home screen, and profile for every user in the home. $10/month per STB. Premiums are extra.

Funny thing is I have unlimited internet with my T-Mo 55+ plan, and I routinely get about 80Mbps at home. They don't currently block iPhone tethering, but they do reserve the right to throttle after 5GB per month usage.
