Dropbox offers up to 5GB of storage for free when syncing photos or videos from an Android phone. You'll need to download the latest version of its Android app to enable this feature. You'll then receive 500MB after the first upload and the remaining 4.5GB as you continue to upload photos and videos. (The space remains yours even if you later delete the content.) That beats last month's mention, which only offered up to 3GB of free space.
