The H examines
free software in handsets
at the baseband processor level.
"There are numerous hurdles that must be overcome before a practical
open source baseband firmware is a reality. Perhaps the largest of these is
concerned with gaining GSM type approval for handsets using the firmware,
without which use with public networks is probably illegal in most parts of
the world, or at least is a violation of a network's terms of service. And
it's questionable whether a handset would ever gain approval if the
baseband firmware can be modified at will.
