how is this method supposed to work? what should i say to amazon when i receive the iphone?

On a completely separate Amazon account. With no linked details. Order a cheap product with a similar weight and dimensions as the iPhone. Then  order the iPhone. Contact Amazon when you receive it and say you received the cheap product your bought and not the iPhone. Since they are similar in weight and Amazon don't have CCTV this method usually works.

Do i have to order it on a different address or same address is ok? Also, do i have to order it from the same exact seller, or i just have to find some product with similar weight and just order it from the alternative account? Thank you so much btw, ill go with this method

Same seller, different accounts and addresses.
