Before you sell or trade-in your iPhone, it is extremely important to erase your personal data on it. 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.
Depending on which version of iOS you're using and your sync preferences, you'll either backup to your computer or Apple's iCloud service.
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.
Back Up via 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.
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.

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.
