When the Apple Store app first arrived on iPhones, it was little more than a shopping portal for Apple goods.
With the latest update, however, new features have arrived to make this app a keeper for any Apple customer who frequents a retail store.
The biggest of these is a retail store button that can not only book Genius Bar reservations or other one-on-one appointments, but can also reserve products for one-day pickup at a store.
As a small tease, the app also has a button for iPhone Reservations, but it currently doesn't reserve an iPhone. (UPDATE: product reservation does work, and with multiple products.)
I used to bury this app deep in a folder, but there's a good chance I might be using it more often now, especially since I'm long overdue to get my own iPhone 4 checked out. I wish I had this a few months ago--it could have saved quite a few phone calls.
