Re: Never mind HP
Yes but they made a deal with Qualcomm that included supplying modems because Intel wasn't going to have a viable 5G modem ready in time (i.e. now, for the 2020 model iPhone)
It will take them some time before they're ready with their own - who knows how far behind Intel was with their effort and how much disruption the handover will cause. Apple was rumored to be working on designing their own before acquiring Intel, so they might even be looking at combining work from the two projects.
So I'd guess it will be 2-3 years before we see an Apple designed modem in an iPhone, though they might put one in the watch (only needs LTE) or the lower end iPad sooner than that as a learning experience before they put it in their most important product.
