One of the things you’re asked to do when setting up your iPhone is specify ownership information. The exact information you are asked to provide includes a name for the device as well as a few other pieces of information that were entered at the time of the device’s original configuration.
If you’ve recently purchased a used iPhone, that device will likely come with registration data from the previous owner already stored in its memory. Likewise, if you’re planning on selling your iPhone to another person, you can remove that content so that it doesn’t get sold along with the device. You can change the ownership information and settings on your iPhone by following a few basic steps.

If you have purchased a used iPhone, connect your device to your computer using the included Apple USB cable (for older iPhones) or Apple USB Thunderbolt cable (for the iPhone 5). Open the latest version of iTunes on your computer and follow the prompt on screen to set up and personalize the configuration of your new device.
If you’re getting ready to sell your iPhone, you don’t actually have to do anything. The new owner of your device will be able to plug it into a computer and configure it as if it were a new device.
Wes couldn’t find any iPhone 4S deals to suit him so he bought a used iPhone and altered the ownership details. He hopes the guide above will be useful to other used iPhone owners.
