Redeem iTunes Gift Cards
Apple has made some changes to the App Store that reduce the need to resort to a computer when purchasing iPhone apps or iTunes music. Now you can redeem iTunes Gift Cards directly from the App Store, topping up your iTunes account if you don't have a credit card and allowing you to buy apps without touching a PC.
