Scrambling to come up with last-minute presents for those lingering on your gift list? If you and your recipient are Facebook users, consider an iTunes Store gift card. You can now purchase virtual iTunes gift cards through Facebook, without needing iTunes at all. To purchase one, you must become a fan of iTunes on Facebook, then click the iTunes Gifts tab to follow customization and purchase instructions. The certificates come in $5 (which isn't available normally via iTunes itself), $10, $15, and $25 values. follow link
