AT&T is now offering customers a cloud storage service with 5GB of free storage for select Android and iPhone users. The service is called AT&T Locker and is available on all Android handsets running software version 2.1 or later and iPhone 3GS and newer devices. Customers can download an app to facilitate cloud transfers through the Google Play store or in Apple's App Store right now.

Much like any other cloud storage service, customers are encouraged to upload videos and images from Facebook, MySpace (do people still actually use that social network?), Twitter or from e-mail. Once uploaded, users can create custom photo and video albums to share with friends and family through the smartphone app or on AT&T's Locker website.

The wireless provider points out that all customers have access to AT&T Locker even if their device doesn't meet the minimum requirements. In such a scenario, customers would need to log in and interact with the service using a traditional computer.

It's unclear at this point whether or not AT&T will be offering higher capacity storage options in the future. This of course is assuming that users will even be interested in the service to begin with. Sure, it is free and people like free stuff, but both Apple and Google already offer their own free cloud storage for their respective smartphone customers.

Both Apple's iCloud and Google Drive serve up 5GB of free storage with the ability to store any sort of data you wish not to mention the numerous other popular cloud storage outfits like Dropbox and SkyDrive. Perhaps AT&T's Locker could serve as overflow or permanent storage outside of these other choices.
