Dropbox, the popular cloud-based storage service, updated its iOS app last night, bringing the software to version 1.5.5. The update includes AirPrint support and some new in-app sharing options.

While the change log isn’t long for 1.5.5, it’s fairly significant. Now, users have the ability to wirelessly print from directly within the app, as well as share their content on Facebook and Twitter…

For those unfamiliar with AirPrint, it’s Apple’s protocol for wireless printing from iOS devices. As long as your printer is AirPrint-capable, you can wirelessly print from your device with zero setup.

The update also adds the ability to share your Dropbox content with Facebook and Twitter friends from within the app. Previously, sharing options were limited to email and clipboard copying.

The new features make the Dropbox iOS app considerably more useful. So even if you’re an infrequent user, I advise you to upgrade. As always, you can find Dropbox in the App Store for free.

What do you think of the Dropbox update?
