Rumor has it that Jos Dreesen may have mentioned these

"Build your own" isn't hacker-friendly???

Shouldn't. It'll probably eat all your REN though.
Speaking of homebrewed cellphones, the hardest part will be getting the
specs. Even with GSM, where the 3GPP has thankfully published everything
for free, reading and understanding all of that is a mamoth undertaking.
<cough>9.02</cough>
Then again, you'll need at least a base station, MSC and protocol analyzer
just to test the damned thing... <sigh> the barrier to entry into voice
telecom is still astronomic, and not likely to lower much if the current
players have any say in the process.

The barrier is also high because of the relative shortage of
experienced RF design engineers. In the modern era, everybody
goes 'digital' and the arcane art of RF design looses out in the
educational system. Companies compete to hire the good
designers, and the designers with a knack for it are busy making
a mint, probably too busy to do a 'hobby' project.
I worked in telemetry for a biomedical device company, and have
seen how 'coddled' a good RF Design engineer is when working on a
critical project.
