This little trick has been around for awhile now but I don’t think we have ever mentioned it on BerryReview. RIM has hidden a little popup in App World that lets you search for an app, game, or theme by using its product ID. You can find an apps product ID easily since it is the number at the end of the URL for each app in App World. For example, the App ID for Facebook for BlackBerry is 680 which you can easily see in the URL for it in App World.
To easily search by an ID in App World you simply hold down the ALT key while pressing the letters STST. That will popup the dialog you see above where you can enter in the ID. This is useful for multiple things like finding apps that are not compatible with your device or apps that have not cleared all the App World cache due to just being released.
Let us know if the shortcut works for you and what you use it for!
