If you want your Pure Connect App to play whilst you use other features of your Apple device you'll need a device that is 'multi-task' enabled. Multi-task support allows your Apple device to run more than one program or app at once and is featured in the following Apple devices:
iPod Touch G3
iPod Touch G4
iPhone 3GS (not 3G)
Tip! You'll need to ensure your device is running iOS version 4.0 or above to ensure successful multi-tasking.
