Apple has finally opened the door to a new promotional code system that allows developers to get full versions of their applications into the hands of reviewers. Now developers can issue up to 50 promotional codes for their application.

These promo codes allow anyone who the developers wish, to download the full version of the application for free. By distributing these applications to reviewers and beta testers, developers can better get the word out about new applications that they have released.

In the App Store, codes may be entered in by using the “Redeem” link. This service is currently only available in the US. We are really curious to see what other changes Apple will make to help developers promote their applications in a sea of over 10,000.
