Today I’m messing around with running Android 1.5 on my old HTC 8125 (Wizard). I don’t have the data network working yet, but I can place a call (but no audio) and send text messages. WiFi is also broken. Whenever the screen should go to sleep, instead of a blank screen, you get scrolled terminal text about the screen sleep function. It’s not practical at all, but it sure is fun.
The Wing Linux project makes it all possible.
Having a semi-functional Android phone in my hands is making me want one though. If even just for a functional Google Voice application (which I can’t get on my iPhone… thanks Apple.)
