iPhone Updates - What is iCloud

What is meant by ?
Most of the people and even the users don't know what iCLOUDS are. iCloud is a suite of free cloud-based services from Apple that helps users store and synchronize digital content across computers and numerous iOS-supported devices such as iPhones, iPads and iPod Touches. iCloud serves as the successor to Apple's MobileMe service and is included free as part of Apple's iOS 5, which first became available in October 2011. The service provides users with an initial 5-GB of iCloud storage for free, with additional storage capacity available for purchase on a monthly basis.
