In June, the US Federal Trade Commission (FTC) began an investigation into Apple's decision to ban developers from using Adobe's Flash-to-iPhone compiler and similar tools to create apps for iOS devices. Apple has also banned Adobe Flash from iOS devices, throwing its full support behind HTML5 as a much more efficient and stable alternative.
The New York Post reported today that the FTC isn't the only governmental authority looking into Apple's Flash ban. Now the European Commission has joined the FTC probe based on concerns that Apple's business practices harm competition. Apple's viewpoint is that the ban is well within its rights, and is necessary to maintain the high level of quality in iOS applications.
The investigation is expected to last another four to six months. In the meantime, Flash is appearing (in an unofficial and not fully functional way) on jailbroken iPhone 4s with the release of Frash earlier this week.
