I just wanted to add this bit. I was able to install android on my N900 without using a external computer I had this thread opened and just copied and pasted commands to the terminal and I was so surprised how everything worked flawlessly aside from the partitioning of the 16GB micro sd card which I had to format in Windows XP but nevertheless awesome instructions.

One major problem I am having is getting Wi-Fi to work but it could just be my encryption WPA TKIP and I did have MAC address Filtering turned it off and said it was able to connect but still unable to browse still happy that I was able to get Froyo installed on my N900!
