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
Arrange Icons on the iPhone/iPod touch Home Screens
Unhappy with the arrangement of your icons? You can move them around as follows: First, hold down on any Home screen icon until all the icons wiggle. Now, drag the icons to their desired locations (drag left or right to get to other screens). Finally, press the physical Home button on your device. (Unlike earlier releases, iPhone Software 2.1 doesn't move just-updated apps to the end of your Home screens, so your icons should be more stationary once you've installed the update.)
Remember that you can replace Apple's default icons in the four persistent spots at the bottom of the screen with your four most-used apps!
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.
