Looking to compile a list of the shipped SPL and Radio versions from the different carriers (especially some of the newer ones).

You can get the SPL version by holding down the power and camera button, and pressing reset with the Stylus. This will take you to the tri-color screen that shows the SPL version. When done, simply press the reset button again to reboot your device.

The radio version appears in red at the bottom of the screen when booting, and on the System->Device screen.
