If you’re planning to pick up a Galaxy S III, Dropbox is offering you 50GB for free. This is a great service for those that haven’t yet signed up for the popular cloud storage service. Unfortunately, this deal is only good for 2 years and if you already have a Dropbox account, I don’t believe they will upgrade for you. This deal is very similar to what HTC has done with Dropbox for the HTC One devices. It’s always good to have extra cloud storage. And Dropbox is definitely one of the best.
