It’s been a week since the next-generation iPhone 5s as well as the colorful iPhone 5c have gone on sale. Despite the iPhone 5s being an “s” upgrade, there are quite a few new features that make the purchase worthwhile, especially for owners of the iPhone 4s or older iPhones.
If you’ve already bought or plan to buy the new iPhone, and planning to trade-in your old iPhone, here are some tips to make sure all your personal data has been wiped off the device’s storage. You’ll be surprised how many people sell their iPhones without doing anything to remove personal data.
Follow these simple steps to make sure that your personal data such emails, text messages etc. cannot be accessed by a stranger.
Backup your iPhone’s data:
Before you erase your iPhone’s data, it is important that you first take a backup of your data, so that you can restore it to your new iPhone.
You can backup to your local machine via iTunes or backup to Apple’s servers via iCloud, or do both to be double safe.
Backup using iTunes
- Connect your iPhone to the computer that you normally sync it with.
- Open iTunes and select your iPhone under Devices in the left-hand navigation pane
- Right-click (or Control-click) the device and select Back Up
Note: If you’ve purchased some items on your iPhone and haven’t transferred these purchases to your computer yet, right-click the iPhone and choose “Transfer Purchases” to transfer the purchases prior to backup.
Back Up via iCloud:
iCloud automatically backs up most of the important data on your iPhone (running on iOS 5 or higher) on a daily basis. But you can manually take a backup one last time before we show you how to delete your personal data.
- Please ensure you’re connected to a Wi-Fi network.
- Launch the Settings app
- Navigate to iCloud -> Storage & Backup
- Tap on Back Up Now
This can take several minutes depending on when your iPhone was last backed up to iCloud.
Note that even if you have iCloud Backup enabled, you can still manually take a backup through iTunes to be double safe.
Turn off Find My iPhone and Activation Lock
If you’re planning on selling an iPhone running iOS 7, you’ll have to make sure that Activation Lock is turned off. Activation Lock is a new feature in iOS 7 that ties your iPhone, iPad or iPod touch with your Apple ID so that if your phone gets stolen, the thief has to know your login credentials to turn off Find My iPhone or erase the phone to factory state.
To turn off Activation Lock:
- Navigate to Settings > iCloud
- Scroll down to Find My iPhone and turn it off
You can even disable Activation Lock remotely via iCloud’s web interface:
- Go to iCloud.com and sign in to your account.
- Open Find My iPhone
- Click on the ”Devices” button to see a list of all your iOS devices
- Click on the iPhone you’ve sold, and tap on the cross icon next to it.
Turn off iMessage
Unless you explicitly turn-off iMessage, there’s a slight possibility that your iPhone continues getting iMessages addressed to you, even after it has been sold. To avoid this turn iMessage by going to Settings > Messages > and turn off the switch against iMessage.
Erase all your iPhone’s Data and Settings:
Now that you’ve taken a backup of your data, you can follow these steps to delete the data and settings from your iPhone.
Note: It is advisable that your iPhone has full charge or connected to a power source before beginning this process.
- Launch Settings app
- Tap on ‘General’
- Scroll down to the bottom and tap on ‘Reset’
- Tap on “Erase All Content and Settings” option
- If you’ve set a passcode, it will prompt you to enter the passcode
- After entering the passcode, it will prompt you one last time if you want to delete data and settings from your iPhone.
- Tap on ‘Erase iPhone’ button
During this process your iPhone will display the Apple logo and a progress bar. The process may take few minutes to several hours based on the version of your iPhone and the amount of data on your iPhone.
If you’ve jailbroken your iPhone then it is advisable to erase all your iPhone’s data and settings by plugging it your computer and clicking on the “Restore” button.
To be on the safe side, before erasing your data, you can sign out and unlink your device from online services like Google, Dropbox, Pandora etc.
Unlink/Unregister your iPhone:
It may be also be a good idea to unregister your iPhone from Apple’s website so that it is no longer linked to your Apple ID.
- Go to: https://supportprofile.apple.com/MySupportProfile.do
- Log in if not already logged in.
- Click on “edit products”
- Click on the “x” to the right of the product.
- Click “Unregister”
Remove SIM/deactivate device
Before shipping or handing your phone off to the new owner, make sure you remove your SIM if you’re on a GSM network or request deactivation of your device by contacting your carrier if you’re on a CDMA network.
Unlock your phone
If you’re planning to sell your iPhone directly to a buyer then you can ask for a much higher value if you unlock your phone, enabling it to run on most GSM networks all over the world.
That’s it! As you can see, it is very simple to prepare your iPhone for resale.
