It's really easy to do!

1) On your device (iPhone,iPod,iPad,android), go to featurepoints.com and download the app
2) Enter the code UVM3BP for a free 50 points to get you started!
3) Download the featured apps to earn points
4) Trade in your points for iTunes cards
5) Trade your iTunes cards for apps and music!

There are also many other gift certificate rewards for paypal, target, amazon, and other things! I started last night and am already halfway to a $10 iTunes card!

Good luck!
