NOTE: You can really screw up your device by messing around with options available in this screen. This is meant for those who know what they are doing and are willing to take some risks.
With that said Thyth let me know that his Thyth-o-matic Engineering Screen Unlock Code Generator has moved to a new website address. As we told you back in May there is a hidden Engineering Screen in the BlackBerry OS. It contains a ton of options and views into what you device is doing and how it is running. The screen is definitely for the geek in some of you to see and tinker with your BlackBerry’s OS.
You can use the easy Thyth-o-matic Engineering Screen Unlock Code Generator at this link to generate a code to view the engineering screen. Access is controlled through a code generated from your application version, device PIN, and device uptime. It is pretty easy to get into the screen but it takes a little work to get it to go away and the options available have no guide to help you through them.
