Dropbox, one of the longest standing cloud-based storage services, has adapted as its user’s digital lives grew. The company offers an iOS app, plus the ability for other software developers to integrate Dropbox access. However, it appears Dropbox is working to implement iDevice-specific features in their desktop client applications. In what appears to be one of the final builds before release, Dropbox is enticing users to test the v1.3 features by offering free storage upgrade opportunities, all the way up to 5GB.

The current desktop client already provides seamless synchronizing of files to and from your personal computer, but this kind of automation doesn’t exist for your iDevice. Dropbox is looking to change that in the next release with a Photo Stream-like service.

Coming in v1.3, connecting an iDevice to your computer will initiate an automatic copy of your Camera Roll, both photos and videos, to a folder named “Camera Uploads.” Now being part of your other Dropbox data, the content will then be automatically synced to the “cloud.” Of course, once synced to the cloud, your priceless moments are safely backed up and available for access by your other devices, plus shareable to friends and family.

Posted on the Dropbox discussion forums yesterday, the Experimental Forum Build – 1.3.12 thread describes the latest changes to the app and rewards for testing the new iDevice import and upload feature. Here’s how the promotion works:

During this beta period, we are also offering additional free space to test automatic uploading of photos and videos. For every 500MB of photos and videos automatically uploaded, you’ll receive another 500MB space bonus, up to 4.5GB total. [Update: To clarify, you can get up to 5GB of free space with this feature, if you count the initial 500MB space for the first photo import].

A standard, free account includes 2GB of storage space and with just a single upload, you add 25 percent more storage capacity. I think, that’s a very kind offer and a pretty slick feature.

We are unsure how long the promotion will last, therefore, anyone interested should give it a try ASAP. The Dropbox beta v1.3.12 client is available for Mac OS, Windows, and Linux.
