Yesterday modaco user Stephen Hyde has posted his work on the Dell Streak. At the moment it is a vanilla build. You can watch of video of his work here the video shows the Streak working with Adobe Flash.
He is working with the cyanogenmod team to get the full cyanogenmod experience on the device. So if you fancy trying out Android 2.2 on the Streak and invalidating your warranty whilst you at it head over to the thread on modaco here.
You can also follow the developers work on twitter here.
