Apple has released an update for its Apple Store app, bringing it to version 2.4. This one adds both Passbook and Siri integration. Now users can send gift cards straight from the app and have them emailed directly to the recipient; it is housed digitally in the Passbook app for convenient access. In addition, Siri's API protocol is now enabled to access the Apple Store's catalog.

What's New in Version 2.4

• Buy new gift cards and email them to friends and family right from the app. These gift cards are easily integrated with the new Passbook app (U.S. only, iOS 6 required).
• Ask Siri to help you find prices and shop for Apple products. (Siri-enabled device required.)
