There is a new rumor suggesting that Samsung may be getting into the cloud-based storage game very soon. In fact, the rumor suggests that Samsung will launch this new service on May 3rd at the same time they debut the Samsung Galaxy S III, or whatever the "next Samsung" will be called. Supposedly, this new service will be called S-Cloud, which isn't really much of a stretch. As far as the rumor is concerned, the service will offer upwards of 5GB of storage, and will try to compete directly with Apple's iCloud.
We won't have to wait too long to find out, as May 3rd is rapidly approaching.
