Quick summary of 47 C.F.R. § 0.459, for those interested in how much will be confidential.

Confidentiality requires a "preponderance of the evidence", as judged by the acting chief (James D. Schlichting). He will base his decision off the following information:

    (1) Identification of the specific information for which 
     confidential treatment is sought;

    (2) Identification of the Commission proceeding in which 
     the information was submitted or a description of the 
     circumstances giving rise to the submission;

    (3) Explanation of the degree to which the information 
     is commercial or financial, or contains a trade secret 
     or is privileged;

    (4) Explanation of the degree to which the information 
     concerns a service that is subject to competition;

    (5) Explanation of how disclosure of the information 
     could result in substantial competitive harm;

    (6) Identification of any measures taken by the 
     submitting party to prevent unauthorized disclosure;

    (7) Identification of whether the information is 
     available to the public and the extent of any previous 
     disclosure of the information to third parties;

    (8) Justification of the period during which the 
     submitting party asserts that material should not be 
     available for public disclosure; and

    (9) Any other information that the party seeking 
     confidential treatment believes may be useful in 
     assessing whether its request for confidentiality 
     should be granted.

Because this information was requested by the FCC, Apple/AT&T/Google can't withdraw the information if the confidentiality request is denied. They can apply, however, for a judicial stay.
