just got mine waived for my wifes iPhone Xs.
yeah i've always gotten a fee. for my 3GS, iP4, iP5, iP6 and wifes iP5s & her iP6 (maybe even my original iPhone) we've always gotten it reversed pretty easily with chatting with them online. Last year with my X i wasn't able to. i didn't upgrade this year but my wife did last night to the Xs so i'll see if we can get it reversed again.
