‘Box.net’ has updated its cloud-storage and collaboration application for iPad and iPhone by adding some much-requested features and improvements for presentations and protecting sensitive data.

“The changes are focused on helping mobile professionals ditch their laptops,” said Dan Levin, CEO of ‘Box.net‘, to ‘Macworld’, when referring to one of the important updates whereby the application supports video out through accessories such as Apple’s Dock Connector to VGA Adapter. “But we don’t just project the entire screen,” he explained, “The improved Box app will project only what is displayed in its content area, allowing you to give a clean presentation and swipe between the slides”.

A much-requested update is the ‘Airprint’ support. The new wireless printing technology is useful as you can now print a document when it is stored locally on your iDevice or even when you have to grab your copy from the cloud. Push the print button and you have the hard copy in your hands with the help of an ‘Airprint’ compatible printer (or other such helpful tools ‘Printopia’).

The new version of ‘Box.net’ comes with added security and authentication options. Now you can set a four-digit locking code on the application as well as using the new Single Sign-On feature for logging into your ‘Box.net’ account using your Google Apps credentials or the Ping Identity service.

‘Box.net’ is available as a free universal application under the Productivity Utilities category in the App Store, but it does require an iPad, iPhone or iPod touch running iOS 3.0 or later.
