Rogue Amoeba has released a new version of Airfoil Speakers Touch, its iOS audio app. The software normally serves as a companion to Airfoil, a desktop client for Mac and Windows PCs that streams audio to iOS devices via AirPlay. The v3.0 update enables iOS-to-iOS streaming, potentially eliminating the need for Airfoil, though the option can only be turned on through a $3 in-app purchase.
