Apple has reimplemented the ability to gift apps to people via an iPhone, iPad, or iPod touch, observers say. While the feature has never disappeared from the desktop iTunes version of the App Store, it mysteriously vanished from iOS in the upgrade from iOS 5 to iOS 6. To bring up the option, a person has to tap the Share button on a title's App Store page. A form lets users pick the email address to send to, a custom message, and when the app will be delivered.
