Adobe Systems Incorporated today announced an update for its Adobe Flash Builder 4.5 and Flex 4.5 software, enabling developers to build applications for Apple’s iPhone and iPad as well as Research In Motion’s (RIM’s) BlackBerry PlayBook tablet PC.

With support for Android-powered smartphones and tablet PCs was released in April 2011, developers will now be able to employ a single platform for building mobile applications, which can be distributed via the Android Market, Apple App Store and BlackBerry App World.

Offered standalone or as part of Creative Suite 5.5 Web Premium and Master Collection, Flash Builder 4.5 enables the creation of applications that work across leading mobile device platforms. This is because they can utilise Flash Builder and Flex, to employ one software tool, one framework and one codebase, in order to create high performance applications that run on desktops, as well as on smartphones and tablet PCs.

“The reaction from developers to the new mobile capabilities in Flash Builder 4.5 and the Flex 4.5 framework has been absolutely fantastic,” said Ed Rowe, vice president of developer tooling, Adobe.

“They are amazed by how easy it is to create great mobile apps for Android devices, BlackBerry PlayBook, iPhone and iPad. Companies can now effectively reach their customers no matter what type of device they have.”

In April Adobe also announced the release of the Photoshop Touch Software Development Kit (SDK), enabling developers to create mobile and tablet applications, which interact with Adobe Photoshop CS5 and Photoshop CS5 Extended software.
