Rogue Amoeba has released a downgrade to Airfoil Speakers Touch, the app that enabled an iOS device to act as an AirPlay receiver. The downgrade was necessary because Apple pulled the app a few weeks ago, and the only way Rogue Amoeba could get it back in the App Store was by removing the AirPlay capabilities. Airfoil Speakers Touch can still receive audio from a Mac or a PC (and from an iOS device or iTunes through one of the above), but it can no longer appear as an AirPlay destination for iOS or iTunes directly. In this blog post, it becomes clear that Apple chose to restrict the app purely for unspecified and capricious reasons rather than any rule infractions. follow link
Find Photos in iPhoto in the Finder
Looking for the file associated with a photo in iPhoto? In iPhoto, to view a photo's file in the Finder, Control-click it and choose Show File from the contextual menu that appears. You can then drag the file's icon into an Open dialog to upload it to a photo-sharing service, for instance, but whatever you do, don't move or rename that file!
Airfoil Speakers Touch Back in App Store without AirPlay Support
(again I don't know anything about how Rogue Amoeba chose to implement this feature, this is merely a possibility)
Such reverse engineering (I believe) is prohibited by Apple's developer policies; plus it is in fact a violation of the Digital Millennium Copyright Act (DMCA), since the private key that was reverse engineered is a form of encryption.
