So, you don't need an iphone, but my friend told me about the Scrabble app. You can download it to your iphone and connect to facebook and play with friends on facebook or on other iphones.
You can use it on facebook and it's free, iphone app costs about $4.99.
The cool thing about it, is you can set the game play to 'one move per week' for a slow game..I think it also emails you/notifies you when your turn is up. You can do it to 'a few movies a week' or the full play. You can chat on it as well.
Just in case you guys wanted some more entertainment during the day :)
