well, it looks like my efforts with facePhone were short lived. i started out creating a better mobile UI for facebook on the iphone. i was challenged, however as the API didn't provide essentially everything i needed/wanted, so i got a limited functionality, but for me, was fine (getting status updates):
well, the guys at facebook (presumably joe hewitt -- i actually contacted him about my efforts and never heard back...maybe this is why :-)).
i haven't tried on edge, but they are loading a lot of content there. looks good though.
