Apple iCloud is necessary to open.

iCloud not only can help you save data and storage space, but also can quickly help us do a cell phone information migration. iCloud has the "Find My iPhone" function, which is a new feature in the iOS7 system. It has anti-theft and anti-loss features, and can remotely locate the current location of the iPhone and send it some special commands, such as locking or erasing data.

If you have more than one Apple device, in the case of logging into the same iCloud account, the contents of contacts, photo streams, memos, etc. of these devices can be synchronized, and of course, data deletion is also synchronized. So, in order to protect your privacy, try to avoid using one iCloud account with other people ****, otherwise your photos are likely to be seen by others. You can also synchronize memos, contacts, Safari bookmarks and more.
