My dribbble client for iOS has finally been released on the App Store: http://bit.ly/BB-Store
Already submitted an update that adds 2 new UIs, Facebook and Tumblr support :)
Feel free to give feedback, complain and request features.
If there is demand for the App i will consider making it a universal app and also the possibility of an Android version.
