The iPhone 17 Air could be the only model to feature Apple’s in-house C1 modem. Here’s what we know so far.

Phone 17 5G modems will be made by MediaTek, as Apple moves away from Qualcomm. Future iPhones will use Apple's solutions instead.

Most of Apple's iPhone 17 lineup won't be using its new C1 modem, Ming-Chi Kuo claims, but they will still benefit from a new in-house Wi-Fi chip design.
