Thanks mate, I assumed I was correct in thinking that.That's correct, but it's easy to pay off rest of the plan next year, sell the phone even to carephone warehouse or something like that and get new model. Last year when I was upgrading from 7 to X, if I gave phone to apple it would equal around £280 (rest of the contract) but carephone warehouse gave me £350.
Going to have to take a trip to my local Apple store next week and have a play with both the xs and xs max. Not sure if I really want a big phone as I’m quite happy with the size of my 6s and the xs is similar to it in size.
But then having all that size with the xs max is making me think more towards the xs max.
