Welcome to iCloud, Apple’s free wireless syncing and online storage service. iCloud makes syncing your contacts, mail, photos, documents and music effortless. In fact, with iCloud, no “syncing” is required—documents and media are all right there for users on every device. While the concept behind iCloud is straightforward, it takes a little tweaking and customization to really get the most out of this free service. And for users who are new to the Apple ecosystem, or unfamiliar with cloud storage, iCloud can seem like an entirely foreign world. Where do my things get 'stored'? What if I run out of storage space? What happened to my MobileMe account? Can iCloud really work with my PC? This guide will take you step-by-step through the process of setting up iCloud on all your devices, including the iPhone, iPad, iPod Touch, Mac and PC. We’ll walk you through the process of viewing and editing the same document across multiple devices without needing to email updated versions or sync changes. Plus we’ll demystify iTunes Match, and help you get started uploading and streaming music across all your devices, including Apple TV.
