iphone

i finally upgraded to an iphone a couple weekends ago and i'm loving it! i peruse the free apps quite often, and have found quite a few things. puzzle games are SO much fun. like this one:

line up 2 - involves matching colored blocks, kind of like dr. mario (pic from itunes)

i've recently had a lot of fun with ovenbreak. basically you're a gingerbread man that hauls ass across the screen, trying to get out of an oven, while collecting jellybeans & life. random and addicting.

i have quite a few others but those are my current favorites. anyone have any suggestions for other fun apps? or useful ones?
