Does anyone know how to use the Facebook App Center?

I thought the intention was that I could share the mobile apps that I am using with my friends, and that I can see the mobile apps that they are using.

So far, I've only been able to see 'Facebook Apps' that my friends are using. Is it possible to see what iPhone or Android apps they are using as well?

It's just a directory of 'apps' to be used on Facebook as far as I can tell. Not very useful unless you want to look up games.

Facebook has had "Apps" for a long time . I think it was a move to help the brigde into the mobile market, something they are trying to do
