According to the Notice of August 9, 2013, the ITC determined that Apple has proven a violation of Section 337 with respect to US 7,479,949 and 7,912,501, but that no violation has been proven with respect to US D618,678 and US D558,757.  Specifically, the Notice at p. 3 states:

[T]he Commission has determined that Apple has not proven a violation based on alleged infringement of the D’678, the D’757, the ‘922, and the ‘697 patents. Specifically, the Commission has determined that the asserted claim of the D’678 patent is valid but not infringed, and that Apple’s iPhone, iPhone 4 and iPhone 4s practice the D’678 patent, but not the iPhone 3G and iPhone 3GS. The Commission has also determined that the asserted claim of the D’757 patent is valid but not infringed, and Apple’s iPhone 3G and 3GS do not practice the D’757 patent.
...
The Commission has further determined that Apple has proven a domestic industry exists in the United States relating to articles protected by the D’678, the ’922 and the ’697 patents, but not the D’757 patent.

As summarized by Eric Schweibenz at the ITC 377 Law Blog:

The Commission’s decision in favor of Apple in this investigation comes on the heels of President Obama’s recent decision to disapprove of the Commission’s determination to issue an exclusion order and a cease and desist order against various Apple products in Certain Electronic Devices, Including Wireless Communication Devices, Portable Music and Data Processing Devices, and Tablet Computers (Inv. No. 337-TA-794).  See our August 5, 2013 post for more details.
