Cool, glad you guys are aware. I like the custom UI implementations. Seems like you guys spent some good time polishing up all of the core animation and stuff. Nice job!
yo, just an fyi, we just updated this bug and it is available now in the app store. one thing you might have to check is go to the Settings app -> Facebook and make sure Exec is switched to On, then the fb login button should be functional again in the app!
