Do any phones other than the Samsung S have gyroscope capabilities? The Samsung S, Android's first official phone to support 2.3 will have gyroscoping capabilities. Do any other phones have a gyroscope?
The Samsung Galaxy S series phones have a 6-axis accelerometer, which is not a true gyroscope although a good approximation.  Hopefully it is actually a true gyroscope in the Nexus S.  Motorola's next big phone is rumored to have a gyroscope, but who knows.  I don't believe any other Android phones have a gyroscope, but the iPhone 4 does.
