Maybe you are now planning to upgrade your iPhone, iPad, or iPod Touch to iOS 7, please make sure you have backed up the content on your device before you do that. Updating to iOS 7 will restore the iPhone settings to their factory defaults, and also delete the contacts, notes, messages, photos, songs, videos, and playlists, etc. And this tutorial is going to tell you how to back up iPhone, iPad, or iPod Touch data before upgrading to iOS 7.
Back up iPhone data with iCloud before iOS 7 upgrade
Before upgrading to iOS 7, you can back up your iPhone data, settings and other content(excluding songs and videos) via iCloud if running iOS 5 or later. Following the steps and back up all your iPhone data via iCloud.
Step 1: Go to Settings > iCloud
Step 2: Scroll the screen and tap the “Storage & Backup” at the bottom.
Back up iPhone data via iTunes before iOS 7 upgrade
If you don’t want to use iCloud or don’t have a iCloud account, you can also use iTunes to back up your iPhone, iPad, or iPod Touch data to the computer. You can easily do this if you are used to manage your device via iTunes.
Note: If you want to avoid “Automatic synchronization” of your iPhone, iPad, or iPod by iTunes, just keep the Shift and Ctrl keys pressed while you open iTunes, which can prevent your iPhone from being automatically synced.
Connect your iDevice to the computer, and open iTunes. Once your iPhone appears on the left iTunes, right click your iPhone’s name and select “Back Up”. Then wait until the backup is over(See how to restore your iPhone from iTunes backup).
Personally, I love iOS 7 and don’t understand why someone would want to delay the inevitable. But I don’t like Apple automatically pushing out the update to unsuspecting users.
