If Qualcomm has its way, it could get even tougher to buy certain iPhone X models. 

The chipmaker on Thursday filed a request with the US International Trade Commission to ban the import and sale of certain iPhones that use Intel's modem. Those would include the iPhone X, 8, 8 Plus, 7 and 7 Plus that run on AT&T and T-Mobile. The phones that run on networks from Verizon and Sprint use Qualcomm's modem and wouldn't be included in the ban.
