i really wish they'd release a version of tetris battle, where you can play vs. other players over wi-fi or even 3G. BTW I'm interested to know people's high scores for the appstore tetris. Mine is 631,500. However, I think you could get a lot higher by utilizing t-spins. The 150 line limit really means you have to concentrate on getting 4-lines/t-spins to get a good score.
