Buying a used iPhone 5. What should be my next steps to register as the new iPhone owner in Apple's eyes, have warranty, etc.
The warranty is established by Apple based on the serial number and nothing else.
If you want to register things, you can do several things:
- Contact AppleCare http://www.apple.com/support/contact/ or via phone
- Self register at https://register.apple.com/cgi-bin/WebObjects/GlobaliReg.woa
- Self register by erasing all content and settings (via Settings App - Reset or iTunes restore) and opting in with an Apple ID to register the device.
Set up your iPhone as a new device via iTunes on your computer and follow through the steps (log in to your Apple ID or create a new one). You will be given the opportunity to register your iPhone under your name.
