New modem details were discovered in Apple’s internal macOS Kernel Debug Kit.

Leak From Apple’s Internal Code

The debug kit was briefly available publicly before Apple quickly pulled it.

Accidental Public Release

Internal code suggests the iPhone 17e may use Apple’s first-gen C1-series modem.

iPhone 17e Modem Plans

Reports suggest Apple may finalize the C1X modem for iPhone 17e as an upgrade over the C1 used previously.

C1X Likely Final Choice

The leaked code indicates iPhone 17e will skip Apple’s N1 wireless chip, which may impact advanced connectivity features.

No N1 Wireless Chip

Without the N1 chip, the iPhone 17e may lack Thread networking support.

Possible Loss of Thread Support

Apple is still deciding between C1X and C2 modems for the iPhone 18 Pro.

Unclear Direction for iPhone 18 Pro

Internal code shows both modem options, suggesting no final decision yet.

Multiple Configurations Listed

Apple’s internal code shows the N1 wireless chip is still planned for iPhone 18 Pro models despite modem changes.

N1 Chip Stays on Pro Models

iPhone 17e is expected in spring 2026, while iPhone 18 Pro models may arrive in fall 2026.
