Pretty self explanatory, right? WiFi2HiFi turns your iPhone into a wireless audio output for your Mac. All you have to do is download the free streaming server for Mac OS X and buy Wifi2HiFi for 99 cents. The setup via your WLAN is managed by the software. However, there is a streaming delay of four to five seconds. So this is really only for listen to music. Of course you may connect the iPhone to your stereo. So this thing lets your stream anything that iTunes via AirTunes won’t!
