Interesting, I did not know that. What are the reasons for this? Military application? Are these laws subject to change?

I always thought that there is no way to separate the CPU from the baseband/communications PU.

It's my understanding that the issue is one of FCC certification and licensing -- the FCC won't approve something which can be easily modified to transmit on non-free frequencies (tools which can usually are sold to hamradio license holders, which should know better and know how much trouble they can get into).
