We have asked both Apple and Intel for comment.
There have not been so subtle indications that this can happen. Apple lured Intel's 5G leader weeks before the Qualcomm deal, for one thing. It has also signaled more than once that it wants to develop its own cellular chipset between job listings and a decision to add jobs to Qualcomm's garden. The company will have all the wireless resources it can get and it is willing to go very far to get them.
An Intel acquisition would not necessarily cause Intel modems to return to Apple devices. As with the acquisition of PA Semiconductor, this will be more about snatching up talent than anything else. Wireless chipsets that come out of an acquisition can take years to complete. No matter what complaints you have over signal quality on iPhones with Intel modems, it probably won't apply here.
