SugarSync is a cross platform app for syncing and sharing files of any sort. It’s great for off site access of your files when on the go and works really well. You can get a free 5GB account or purchase more data storage for a reasonable fee. Files can be synced across computers and devices via a Magic Briefcase or you can access files that are specifically on a single device. Uploading and downloading files via the BlackBerry app is very easy to do and the app while small is very powerful.
