Apple introduced iCloud at WWDC 2011 (WorldWide Developers' Conference), a set of free new cloud services that work with applications on the iPhone, iPad, iPod Touch, Mac or PC to automatically and wirelessly store content in iCloud and automatically and wirelessly push it to the aforementioned devices. When anything changes on one of your devices, all of your devices are wirelessly updated almost instantly.
A press release quotes Apple CEO Steve Jobs,"Today it is a real hassle and very frustrating to keep all your information and content up-to-date across all your devices. iCloud keeps your important information and content up to date across all your devices. All of this happens automatically and wirelessly, and because it's integrated into our apps you don't even need to think about it. It all just works."
