I preordered an iPhone XS Max last year when Xfinity opened up preorders and received it on launch day. I'm eligible to upgrade now (verified online) but says I need to bring my current phone into a store. Does anybody know if I'll be able to preorder through their site when preorders for the new iPhones begin or will I not be able to preorder and need to go into a store and try to score one on launch day? Thanks in advance!
