Cross-Platform Apps? (iPhone & Android)

[honestlyx21]

Are there any apps that you know of that are available for both iPhone and Android that can communicate?

For example, Words With Friends is a Scrabble-like app on the iPhone. On this app you can play with others who have it on iPod touches/iPhones. (I know there isn't an Android app, but if there were, could it communicate between the two?)

So if its possible are there apps currently available?

The only one I can think of right off the top of my head is Bump.
