Why not a nexus chipset ?

[Sylvain Munaut]

1) We're not the one that decide which chipset specs are leaked ...
Also, we had a complete working gsm stack example for that chipset as
a guide (the specs are not always complete / correct / enough). There
is nothing even closely like that for any of the newer chips that I
know of.

2) Most modern chipsets have cryptographic securities preventing the
loading of a custom baseband firmware on them.

3) 3G / 4G chipsets are _vastly_ more complicated. As it is for the
calypso there aren't that many people with the skills to work on the
firmware, so for more complicated chipset the situation might be even
worse.

4) When you're experimenting with stuff that can brick / destroy your
phone (and I have a couple of dead ones ...), you don't want to do
that on your brand new 600$ phone.

Cheers,
