Want to send your favorite iPhone fart app to all your friends? You can do that now! Apple has added an app gifting function to the iTunes store (the one on your computer, not the App Store on your phone). To find it, just click the little arrow next to the price on any app, and choose to "Gift This App." There, you'll be able to specify recipients, write a personal message, and send the certificate either through email or by printing it out.
Sadly, this functionality arrived too late for you to send out copies of the $400 Zits & Giggles -- Apple removed the game following Tommy Refenes's Indie Game Maker Rant.
