I can pretty much confirm that the FM Radio will not be included on the Sprint version of the Touch Pro, if you take a look at the
CNET First Look video of the device, at one point the reviewer scrolls through the installed applications and the FM Radio launcher is no-where to be found. Of course these doesn't mean we can't just reinstall the cab files or it... we'll have to wait and see what hardware modifications Sprint requested from HTC besides removing the front facing camera.
