We always go camping Easter weekend, and that was also the start of MLB. Being a Yankees fan I wasn't going to miss opening night Yanks vs. Sox. So I put the Droid and Verizons 3g to the test. With my Droid hooked to my laptop running PDA.net I was capable streaming movies, Bernard Hopkins Roy Jones Jr. PPV fight and the Yankees Red sox game with ease!
I guess he was using a website that streams live games. But there's a few apps that you can watch prerecorded shows. TV.com is a free app where you can watch CBS, CW, Showtime, amongst others. Pretty sweet.
