On the heels of the preview of its Jelly Bean-flavored Android app, Dropbox has updated its iOS softwarefor mobile devices as well. This time around, the cloud storage outfit threw in sharing directly to Facebook and Twitter. Simply select your social media outlet of choice from the menu and proceed to type the appropriate message. A link to the file will then get comfortable on your timeline once you post the update. If you need to keep matters a bit more private, you can include the info in a Facebook message as well. For those looking to print directly from their cloud libraries, AirPrint support is also included in this version (1.5.5). If you haven't snagged the update just yet, the iTunes link below will lend a hand with said task.
