You go through a quick online wizard, inputting your model and then the wizard will ask about the condition of the device. Apple will then reveal the trade-in price dependent on the variables.

You must include a power cable in the package you send back to Apple and the company will return you a gift card to be redeemed on a new iPhone.
Apple is expected to launch the new iPhone on September 12th and ship it on the 21st.
