App Suggestions

Does anyone have any app suggestions for the iPhone/iPod Touch?

Specifically, I am looking for a good crossword app as well as games that I can play with TEA.

Why am I looking for a crossword app? It seems like a good idea and I want to help with my Scrabble/Words with Friends vocabulary.

I would prefer turn based games as opposed to real time.

TEA and I have a game of Words with Friends going, if you are looking to make that suggestion.

(I am also looking for games that I can play with my father who is becoming an iPhone owner within the next week or so. Welcome dad, thanks for joining us.)
