In a letter to the FCC dated shorty prior to the company’s official unveiling of the iPhone 4, Apple asked the regulatory body (PDF Link) for a 45-day confidentiality window on certain documents.
Specifically, the test setup photographs, external photographs, internal photographs, and the user manual.
In the letter, Apple says that “although Apple has begun to market the device publicly, these documents reveal technical and design information that has not been publicly disclosed in such marketing and that is protected by Apple as confidential and proprietary trade secrets.” As is standard practice, Apple in the same letter requested permanent confidentiality for more sensitive documents, including schematics for the applications processor, cellular radio, and Wi-Fi + Bluetooth.
