Three have issued a video guide to using Dropbox to transfers files from your PC to your smartphone.

Dropbox is a remote storage service that enables you to easily upload music, movies, documents and much more , which you can then download to any other supported device, including smartphones.

The advantage of using a "Cloud" based storage service is that your data is accessible at any time from any supported device. Additionally, if you lost your mobile or got a virus on your computer,  you wouldn't lose your all your important photos, videos and documents.

The video, brought you to by Kellee Taylor, quickly goes through the steps involved in transferring music to Dropbox and then downloading or streaming it on your mobile.

The only downside to using Dropbox is you need to use mobile data to retrieve the files, but you can use WiFi or if your on Three you don't need to worry as they have packages with unlimited data. Click here to visit the Three store to see the latest deals.
