To get the most out of iCloud, update to the latest system requirements. Then set up your iPhone, iPad, iPod touch, Mac, and PC.
iCloud requires iOS 5 or later on iPhone 3Gs or later, iPod touch (3rd generation or later), iPad, or iPad mini; a Mac computer with OS X Lion v10.7.5 or later; or a PC with Windows 7 or Windows 8 (Outlook 2007 or later or an up-to-date browser is required for accessing email, contacts, and calendars). Some features require iOS 8 and OS X Yosemite. Some features require a Wi-Fi connection. Some features are not available in all countries. Access to some services is limited to 10 devices.
