Words With Friends is a very Scrabble-esque app, available for Droid and iPhone. It’s free for both, plus iPhone apparently has a paid version. Basically, it’s Scrabble by mail - one player makes a word, then, at their leisure, the other player goes. Games can last for days.
If anyone plays or wants to try it, download it from the Android market or app store, and make an account.
My account is hrhomer - you can create a game with me, and I’ll play…
