ummmmm okay I've clearly never done this before :D I scratched off the thing on the back but I can't figure out where you enter that on iTunes…
2.Open iTunes. 3.In the Source list (on the left side of the iTunes window), click iTunes Store. 4.In the upper-right corner of the iTunes Store window, click the Sign In button. If you are already signed in, skip to step 6. 5.Sign in to the iTunes Store using your iTunes account information. 6.In the QUICK LINKS window in the right-hand column, click Redeem. 7.In the resulting screen, enter the 16-digit code printed on the back of the card (it starts with an "X"), then click Redeem. 8.Once you've successfully redeemed your code, the credit amount will appear next to your account name in the upper-right corner. Each time you purchase items, iTunes will deduct funds from the credit until it's depleted. If a pending purchase exceeds the credit amount, iTunes will ask you to enter a credit card number. You do not need to re-enter your gift card number to make multiple purchases.
I got that information from the iTunes store :)
Wow you looked on iTunes…why didn't I do that XD
