Redeem iTunes gift cards on-the-go

When Apple released the iPhone / iPod touch 1.1.3 update; there was one new option in the iTunes Wi-Fi Music Store that wasn't given much attention. With the inclusion of the update, you can now activate an iTunes Gift Card right from the Wi-Fi store.

You can find this new "Redeem" option in the "Downloads" section of the Wi-Fi store. Just tap the button, enter in the code from the back of the gift card, and then click "Redeem" again, and the gift card will be added to your account. The only problem that I see about this option is the fact that you cannot view (on the go) how much money is still credited to your iTunes account, however, this is a welcomed feature to the iTunes Wi-Fi Store.

[Update:] In the comments, some readers have noted that in the "Downloads" screen of the Wi-Fi Store, you will see your current iTunes account balance.
