Docking and playing your music from an iPhone dock or speaker system is great, but you lose all the other cool functions on your phone. You can stream music from your iPhone wirelessly via Bluetooth to a dock or stereo speaker and retain all the functionality of your phone with the iStream DockFree Audio Receiver. Listen to music while texting, e-mailing, playing games and web browsing. Turn up the volume of your favorite song right from your phone. Accept phone calls - music will pause and resume after your call is concluded.
