The latest update to the Apple Store app isn’t huge, but it does contain a couple of neat perks. Version 2.4 allows you to buy gift cards and email them to family and friends from the app. Those with iOS 6 will be able to use those gift cards with Passbook.
But the neatest thing about the update is that it integrates Siri into the app. You can now ask Siri to find prices and shop for Apple products. The urge to find the cost of a Lightning cable by voice alone ever strikes, now you can do so through the Apple Store app.
