The app that lets users wirelessly access their Mac applications and Windows programs on-the-go, while running Parallels Desktop for Mac, was just updated to version 3.1.530.

Parallels Mobile allows users to remotely control all the software on a computer from an iOS device, but today’s upgrade includes iOS 5 compatibility and new iPad optimization. It also offers support for international keyboard layouts when working in Mac applications, fixed scrolling in Mac and Windows, and a host of other improvements.

The app requires Parallels Desktop for Mac version 6 or 7 (Amazon currently offers v7 for $62), but 9to5Mac found Parallels Desktop 7 to be a huge leap ahead of its predecessor. This is especially true for Lion users that want to run the odd Windows app, try Windows 8, or for devs that just want to run another instance of OS X.

Parallels Mobile is $4.99 in the App Store.
