This past Tuesday, Apple announced the new iPhones, the iPhone 5s and the cheaper, plastic iPhone 5c, which, I must confess, looks cool. If I were going to go for a 5c, I’d definitely be after the green one.
Simply plug your iPhone into your computer. If iTunes is set to open when a device is connected, then iTunes becomes selected and you will see your device appear in the left sidebar under Devices. Select your iPhone. (If iTunes is set to open manually, simply open iTunes and you will see your device).
Under the Summary option, as shown in the screen shot below, you will see a choice of where to back up your iPhone, either to iCloud or to the connected computer. Choose Back Up Now. You can also see when you last backed up your iPhone.
iTunes will now create a full back up of all your iPhone’s text, contacts, schedule, etc. If you set Backups either to Automatically Back Up to iCloud or your computer, iTunes will perform a back up whenever you connect your iPhone to your computer. Whichever back up option you choose, make sure you back up before you upgrade to iOS 7.
