I have been upgrading my phone every year and I recently switched to T-Mobile last year. If I do a trade in it applies the credits over two years, so does this mean that if I upgrade again after one year I will stop receiving the full value of the phone, resulting in only getting half of the value of the phone? If so, what is the best way to upgrade every year? Sell the phone on my own and not trade it in?
Thanks
