User: How can I upgrade my iPhone to the latest model?
Assistant: The latest model iPhone is called “iPhone X”, and you can upgrade your phone to one by ordering it on Apple’s website.  The phone costs approximately $999.99 USD, and this will get you a new iPhone and a new phone case, screen protector, and Lightning Cable (which you can use to charge and connect your phone).  Note that you cannot upgrade your phone through the Apple Store; you need to order it online.
