It was rumored that Apple Store App has been updated to include Personal Pickup and EasyPay which is an in store payment facilities and also now you will able to track your order right from the App.
Now let me explain these three terms one by one,
Personal Pickup: It means that you can buy in the app and it’s your choice to pick up your order from any Apple Retail Store. Now here one thing is important that most in-stock orders are only available for pickup within one hour. (U.S. only)
EasyPay: Now you can purchase select accessories in the store app more quickly by simply scanning the barcode and complete your traction in the app. (U.S. only, requires iPhone 4 or iPhone 4S)
Track Your Order: This mean that you will be able to see the status of your current or previous order if any from the order status section which is found in the ‘More Tab’.
This support is not only of U.S. but also there is added support for Canada and China, but Personal Pickup and EasyPay features are available in U.S. only. This new App is available for iPhone, iPad and iPod Touch. Well it is not a universal binary so either you will need to hit the 2x button on the iPad; a very strange decision!
