There's a little trick to see a product ID of the application. RIM has been hiding a small popup on App World that allows us to find an application, games, or themes using the product ID. We can find the product ID applications with ease because of the number at the end of the URL for each application in the App World.
For example, ID App for Facebook for BlackBerry is 680 which can easily be seen in the URL. To easily search for an ID in the App World is actually quite easy. With metahan the ALT key while pressing the letter STST, then the popup seen above.
So what's the point of this little trick?. This is useful for some things, like finding an application that is not compatible with your BlackBerry device or applications that have not cleared all of its cache App World.
