Adobe has released an update to its Flash Builder 4.5 and Flex 4.5 software to enable developers to build applications for iPhone, iPad and BlackBerry PlayBook (support for Android devices was released in April).

Adobe says that developers now have a single platform for building highly expressive mobile applications that can be distributed via the Android Market, Apple App Store and BlackBerry App World.  

Flex 4.5 also includes new tools designed to allow developers to rapidly build applications for the desktop, Web and top mobile platforms. Using best practice code templates, code completion and code generation features in Flash Builder 4.5, developers can accelerate the creation of Flex and ActionScript applications and deploy them using Adobe AIR software. Adobe says that by the end of the year more than 200 million mobile devices are expected to support AIR applications.

Apps already available that have been built using these new tools include task manager Conqu, and matching and word games Mr. Mixit and Pyramix,

Flash Builder 4.5 Standard costs £181.20 plus VAT.  Flash Builder 4.5 Premium costs £413.00 plus VAT and is also available as part of the Adobe Creative Suite 5.5 Web Premium and Master Collection.
