Backbreaker Football is on sale until Sunday at 50% off (or $1.49). I don't know the 'reason' for the sale given that it's week 3 of the NFL's preseason and opening week of the regular season would have made more thematic sense, but at $1.49 I'll bite even though I own it on my iPod Touch. It also now supports Froyo's App2SD feature.
Edit: I'm a bit surprised by this, but the game only takes up about 600k of internal memory now that it installed most of its data to the SD card. This game is a must have for football fans with it's new small footprint.
