Flash Professional CS5 will enable you to build applications for iPhone and iPod touch using ActionScript 3. These applications can be delivered to iPhone and iPod touch users through the Apple App Store.*
A public beta of Flash Professional CS5 with prerelease support for building applications for iPhone is planned for later this year. Sign up to be notified when the beta starts.
At MAX 2009, Adobe showed a number of applications and games for iPhone that have been built using a prerelease version of Flash Professional CS5. These applications are available now for you to download from the Apple App Store.
