Samsung and SugarSync are already cozy with each other, having struck a deal to put SugarSync’s cloud file sharing on Samsung’s AllShare Play-equipped TVs. That relationship just got a lot closer: SugarSync will now be a mainstay for Samsung’s rather successful mobile devices. Starting with the Galaxy S III, any Samsung phone or tablet that supports AllShare Play will have SugarSync built-in, whether it’s for looking at files and media from back home or just to upload the phone’s own photos and videos for sharing later on. The service still offers a free 5GB of storage as a baseline and will scale up to 500GB if you’re willing to fork over up to $ 40 a month. Between this and a Dropbox deal for most carriers, Samsung has the cloud largely sewn up on its handhelds — if you can’t access it, it probably doesn’t exist.
