628: There’s a Certain Smell

What It Covers

Apple's custom C1 cellular modem debuts in iPhone 16e, marking a strategic shift from Qualcomm. The episode covers modem development complexity, iPhone 17 design leaks featuring full-width camera bars, and John Siracusa's Hypercritical app launch for reclaiming disk space.

Key Questions Answered

• •Cellular Modem Complexity: Apple's C1 modem required testing with 180 carriers across 55 countries and represents their most complex technology ever built. The chip uses 4-nanometer process for the modem and 7-nanometer for the transceiver, demonstrating the sophisticated engineering required to decode signals as weak as 31.6 femtowatts (0.0000000000000316 watts) while managing interference and multiple frequency bands simultaneously.
• •Strategic Modem Rollout: Apple deployed the C1 modem first in the iPhone 16e rather than flagship models, providing a safer testing ground for unproven technology. The C2 modem arrives in 2026 for higher-end phones, with C3 expected to surpass Qualcomm capabilities by 2027. Apple plans eventual integration into the main processor by 2028 for improved energy efficiency and reduced costs.
• •Qualcomm Licensing Reality: Apple must pay Qualcomm patent royalties regardless of using Qualcomm chips, capped at a percentage of $400 phone value even for thousand-dollar devices. This licensing requirement persists until Qualcomm patents expire, meaning Apple's custom modem reduces component costs but not licensing fees. The FTC versus Qualcomm court decision confirms OEMs pay per-unit royalties independent of chip sourcing.
• •iPhone 17 Design Changes: CAD renders show iPhone 17 Pro models featuring full-width rectangular camera bars spanning the entire phone back, similar to Pixel design language. The standard iPhone 17 retains current camera layout while the ultra-thin 17 Air at 5.5mm thickness includes a single camera with full-width mesa. Camera lenses still protrude from the mesa on one side, meaning phones continue wobbling on flat surfaces.
• •App Store Review Inconsistency: Hyperspace app experienced three submissions with different outcomes - instant rejection for unclear functionality description despite extensive documentation, approval on resubmission, then metadata rejection for missing privacy policy URL in description on third attempt. The required non-clickable URL serves no functional purpose on any Apple platform, demonstrating arbitrary enforcement of submission guidelines across review cycles.
