Summary:
- Apple is reportedly already testing its own cellular modem chip, dubbed the "C2," which could eventually replace Qualcomm modems in future iPhones.
- The development of the C2 modem is part of Apple's ongoing efforts to reduce its reliance on third-party suppliers and bring more components in-house.
- Transitioning to its own modem chip would give Apple more control over the iPhone's cellular connectivity and potentially improve performance and power efficiency.
