iPhone 18 Pro leak points to Apple C2 modem split and a major Sony camera upgrade
A massive 630GB data leak tied to Tata Electronics, one of Apple’s suppliers in India, is continuing to reveal new clues about Apple’s next-generation Pro iPhones. The latest information focuses on the iPhone 18 Pro and iPhone 18 Pro Max, offering a closer look at potential modem choices, regional hardware differences, and a new main camera sensor.
Recent leaked materials have already hinted at the physical design of the upcoming iPhone 18 Pro models, including views of the rear layout, bottom edge, internal structure, and logic board design. Now, a deeper look at the data suggests Apple may be preparing two different modem configurations depending on the market.
One of the biggest surprises involves Apple’s in-house C2 modem. Many industry watchers expected the iPhone 18 Pro lineup to be the first Pro-series iPhones to fully move away from Qualcomm modems. However, the leaked details suggest that may not happen worldwide.
According to the new information, iPhone 18 Pro and iPhone 18 Pro Max models sold in the United States may continue to use Qualcomm modems. Meanwhile, international versions, including models intended for Europe and large parts of Asia, appear likely to use Apple’s new C2 modem.
The reason seems to be mmWave 5G support. In the U.S., mmWave 5G is available in some major cities and remains an important part of carrier networks, especially for high-speed coverage in dense areas. Qualcomm modems have long supported mmWave, while Apple’s C2 modem reportedly may not include the same level of support.
Leaked logic board identifiers appear to support this theory. One board number, 820-04340-06, is believed to refer to a U.S. version of the iPhone 18 Pro with an mmWave connector and Qualcomm components. Another board number, 820-04305-06, appears to represent an international iPhone 18 Pro logic board without the mmWave connector.
If accurate, this would mark an important step in Apple’s long-term plan to reduce its dependence on third-party modem suppliers, while still keeping Qualcomm hardware in regions where mmWave 5G remains necessary.
The leak also points to a noteworthy camera upgrade. The current iPhone 17 Pro and iPhone 17 Pro Max reportedly use Sony’s IMX903 sensor for the main camera. For the iPhone 18 Pro generation, the sensor identifier appears to change to 0x905, which strongly suggests a move to Sony’s IMX905 sensor.
At this stage, the exact benefits of the Sony IMX905 sensor are not fully known. It is unclear whether Apple will use a larger sensor than the existing 1/1.28-inch unit, but the possibility is drawing attention because a bigger sensor could improve light capture, dynamic range, low-light photography, and overall image quality.
Another clue comes from the rumored thicker camera module on the iPhone 18 Pro and iPhone 18 Pro Max. A larger sensor could explain the increased thickness, although it may not be the only reason. Apple is also expected to bring a variable aperture to the main camera, a feature that could give users more control over depth of field and light intake while improving performance across different shooting conditions.
A variable aperture would be a major upgrade for iPhone photography, especially for users who want better portrait shots, sharper landscapes, and improved low-light results without relying entirely on software processing. Combined with a new Sony sensor, the iPhone 18 Pro camera system could become one of the most significant upgrades in Apple’s recent Pro lineup.
Still, it is important to treat these details with caution. The leaked Tata Electronics files may include information from earlier stages of development, and Apple can still make changes before mass production begins. Hardware identifiers, internal diagrams, and component plans are useful clues, but they do not always reflect the final retail product.
Even so, the latest iPhone 18 Pro leak paints an intriguing picture. Apple may be preparing a region-specific modem strategy, with Qualcomm modems staying in U.S. models while the Apple C2 modem reaches international versions. At the same time, the shift to a Sony IMX905 main camera sensor and the possible addition of a variable aperture could make the iPhone 18 Pro and iPhone 18 Pro Max major upgrades for mobile photography.
If these details hold true, the iPhone 18 Pro series could represent a key moment for Apple: a step forward in custom modem development, a more advanced camera system, and another push toward tighter control over the hardware inside its flagship smartphones.
