As a former USCC customer, this frankly should not have been surprising to him. Its reason 1a why our family left them. Reason 1b was no LTE service, still to this day, while Verizon has had it in my locale for 2 years now.
Anyway, they've turned into a Samsung/Apple only carrier. Even then, they didn't get the 5s on launch day. It would have been nice to see them pick up the ATIV SE, but it looks like now they've even taken the ATIV Odyssey off their web page. It does look like as a carrier they are done with Windows Phone. Honestly, I would still encourage him to switch carriers. Their contracts offer no advantages over Verizon or AT&T, unless he stayed grandfathered and paid full price for his iPhone. My monthly total actually reduced a little after switching, with much better cell service/covereage and of course, phone selection.
If he just got it, within the last day or so, I don't know how easy it would be to get out of it. I would just hate to see him locked into 2 years on USCC.
