That’s according to the New York Post, which names people that know about the matter as the sources.
The investigation will centre around modifications that Apple made to terms and conditions with developers of applications fot the iPhone.
And, according to the Wall Street Journal, the investigation has become a matter for discussion after both app developers and competitors complained about the changes to licence agreements made by Apple for both the iPhone and the iPad.
The Justice Department and the FTC have, apparently, still to decide which of them will start the investigation, which may or may not lead to further action against Apple.
Apple has a firm grip on the type of software used by developers to create applications for the two devices, and insists they use its own rather than third party tools.
Furthermore, third party ad networks believe that Apple’s grip on the way data is transmitted from the devices could lead to anti-competitive problems. The NYP story is here.
