iCloud. Like all other iOS devices, the iPhone 4S will have access to iCloud, Apple's handy new online storage system that has three key features: iCloud Storage, which gives you 5GB
of free storage for email, documents and backup; iCloud Photo Stream, which wirelessly pushes any pictures you take with your phone or tablet
onto all your other devices; and iTunes in the Cloud lets you sync up all the music you've purchased from the iTunes store and push it out to your
devices. Apple is also offering iTunes Match, a software program that scans over music in your iTunes Library that you haven't purchased from the
store and tries to find a match for it on its online database of more than 18 million songs. Unlike other iCloud services, however, this one isn't free
and will cost you $25 per year to maintain.
