If you own a PS3 and you own an HD2, today’s your lucky day since XDA forum member HackMimic has written an WM6.5 app to make things easier for those of you who want to jailbreak or downgrade your PS3.
The XDA member wanted to make it easier for himself and hence others, so has posted his app including detailed instructions on how to use it.
The PS3DJB app will install all files to your SD card needed to jailbreak and downgrade your PS3 with your HD2.
You will need to place the Android build of your choice on the root of your SD card before installing, and download and install a few cab files on your WM OS in order to transfer the required files to your Android build. Once you launch the PS3DJB app, follow the instructions for the jailbreak process. You will need to plug your HD2 into your PS3.
For detailed instructions including FAQs and links to required downloads, take a look at the application thread.___________________
