So we've already seen Apple's press release that unlocking apps might void warranties or even brick devices. And we know Apple is selling iPod games via iTMS. And we see all the black space on the iPod touch home screen. Why wouldn't Apple start selling real apps via iTMS? If you can download Tetris, you can just as easily drop $5 on Mail.app or Maps.app. My question is: Why wouldn't Apple be planning to do this?
