This is the official Britney Spears iPhone app, which reached #42 in the paid apps and #2 in music. It allows Britney fans to view photos, twitter posts and news articles on their iPhones. It also includes a feature where fans can put their photos in the heads of Britney's dancers. Shake it and Britney will say, "It's Britney Bitch!" It was the first paid app that prod produced and ended up going through many revisions which taught us a great deal about the software development cycle. We also put a heavy emphasis on complying to Apple's User Interface Guidelines which was an important introduction to iPhone development best practices.
