Did you add a contact to your iPhone running iOS 7.1.2 only to find that it doesn't show up in your Contacts app? Or perhaps it isn't syncing to your other devices via iCloud like it's supposed to. I recently had a friend experience this issue and a few days later I did too. As it turns out, the problem isn't actually iCloud at all. Luckily, the fix is super simple!
Apple has quietly implemented in-transit encryption for iCloud emails. Emails sent to or from an @icloud.com or @me.com address are now encrypted. Previously Apple only encrypted emails sent between iCloud addresses. The encryption will help to secure emails moving between servers from snooping, particularly on the part of the government.
If you purchase movies, music, and TV shows from iTunes, it doesn't matter what device you purchased them on, in most cases they're available to you via iTunes in the Cloud, part of iCloud, from anywhere. Aside from your iPhone and iPad, that also includes iTunes on your Mac or PC.
If you've purchased books from iBooks, you can download and enjoy them across all your devices, and it doesn't even matter what device they were purchased on. If you don't have automatic downloads enabled or you accidentally deleted a book, you can easily get them back whenever you'd like thanks to iTunes in the Cloud!
Not only can you re-download apps that you've previously purchased, but thanks to iTunes in the Cloud, you can also re-download any music, movies, or tv shows that you've purchased. Whether you accidentally deleted something or want to download something to one device that you downloaded on another, you can easily do so via the iTunes app!
Apple is starting to use two-factor authentication for iCloud. The added security appears to be rolling out in phases so some users are beginning to see this feature when they log into iCloud while others may have to wait until it gets deployed for their accounts; we can confirm that it is active on several accounts here at iMore.
If you didn't originally set up your iPhone or iPad with iCloud, or if you want to use a different iCloud account than you do for iTunes purchases, you may need to sign in and set up iCloud outside of the initial setup process. In some cases, you may simply want to add an additional account to your device, you can add an iCloud account at any time via the Settings app.
While iCloud is meant to be used mainly on your iPhone, iPad, and Mac, times may arise when you'll need access to your mail or calendar from a public computer. Perhaps your iPhone is dead and you need to use a friend's computer, or you're on holiday and don't have mobile data but there is an internet cafe or terminal close by. Either way, you can quickly and easily access mail, contacts, calendars, and many of the other iCloud services from any web browser.
Any Mac running OS X Lion or later comes with iCloud support built right in. If you've already got an existing iCloud account or need to set one up, it's incredibly easy to get all your contacts, calendars, and your iCloud mail account linked up with your Mac.
If you're a Windows user, that doesn't mean you can't take advantage of the iCloud service. While Mac users may have it built right in, Apple also offers an iCloud Control Panel for Windows users that lets you manage some of your iCloud settings from your desktop, including Photo Stream, calendars, contacts, and more.
