Apple's decision to block apps created by third party compilers, i.e. apps not created via Apple's documented APIs, has sparked a potential antitrust probe towards the company. For now, both the US Department of Justice and the Federal Trade Commission are still in debate on which agency will initiate the antitrust inquiry.
Ars Technica - The US Department of Justice and the Federal Trade Commission may be considering an investigation into Apple's decision to block iPhone OS apps created by many third-party compilers. According to insiders speaking to the New York Post, the two organizations are "locked in negotiations" over which one will launch the antitrust inquiry, and the decision is mere "days away."
But don't take this as a potential for Adobe's Flash to make its way into the new iPhones. With the rate at which antitrust inquiries are held (if there's any in the iPhone OS case), it could take a while. So in the meantime, sit tight, and see how the whole story spans out over here.
