The App Store application has just been updated to show your purchase history and to allow you to download any application that is not installed on the device.

When you go to the “Updates” section of your App Store app application, you will now see a “Purchased” button. This will take you to a list of all the applications you have ever purchased. You can also select the “Not on This iPhone” option to see apps that have been downloaded to your other iDevices…

You can then easily redownload to your device effortlessly, and completely free of charge.

You need to be on iOS 4.3.1 or above to enjoy this new feature.

How do you like this new option? Quite handy, isn’t it?
