That's what I was reading as well, they're using a combination of lower-end Qualcomm and Intel modems to supplement them.

I suppose it'll just come down to how quickly Gigabit LTE get's rolled out? If it's within the next year than these phones will essentially be out-dated on release until Apple makes a new version with a better modem while the competition is "future-proofed" in that regard. If it's longer than a year or two, by that time they'll have caught up on sourcing competitive modems and the issue is moot; bit of a risky gamble I suppose.

I mean current speed is nice, but let's be honest from a consumer standpoint speed/connectivity is a huge factor in not only handset sales but provider sales as well. I would have thought at least the X would have been future-proofed in that regard since they did such a good job on the phone otherwise. Oh well, still a powerful platform.
