It works from NAND, wich means your windows mobile will be gone. So you need to be very sure what are you doing before do something.
So if you still want to flash android, you need to put NIKEIMG.nbh on the rootof sd card,
androidinstall.tar and androidupdate.tgz to /andboot/ folder.
Turn off the device, hold CAMERA and POWER buttons, until you get to bootloader, then press power again.
Now press reset or pull battery off, then power on your phone. After splash screens you will see some fast running output, when you see something like "Hold center or volume up button to install" you need to hold center button. All the other stuff is like usual HARET installation, exept you need to put systrm and data on NAND in installer. After install complete, you need to install update before exit.
