on some android devices, when you unlock, it gives you them circles where you can draw a pattern to unlock the device

can you get that on the HTC HD2 LEO?

i know you can put android os on the phone, but i dont have a clue how to do it with all the flashing radios or whatever you have to do. tried and failed :P

i am quite smart and handy when it comes to things like this, its just i have had my first smartphone with windows mobile 6.5 for a few hours and REALLY want that android unlock password pattern thing. i already have the android slider thingy

thanks
