App Store app from Apple now available

Apple has been busy with announcements over the past 24 hours with the iPhone 4 reservations and pre-orders going live, introduction of the new Mac mini and also their new App Store app (compatible with iPhone, iPod touch and iPad - iPhone OS 3.0 or later required).

The new app lets you shop the Apple Store, buy products and accessories, read customer review, find an Apple Retail Store, check on store events, set up Personal Shopping, Genius Bar and One to One appointments and more.

Also, as Jerry over at MindTribe pointed out (and did) you can pre-order or reserve your new iPhone 4 in just a few taps without entering your AT&T account information.

The Apple Store app is free and available now.  Do you think you'll download it?  Do you think you'll use it?  And if you do use it, what will you use it for?
