[Replicant] basic phone with 100% free software to use on Verizon?

Hi Bruno,

I got a hold of your inquiry because it was reposted on the Replicant
mailing list, and I decided to take the liberty of giving you my input
on this subject.

I have to disappoint you in that the chances of a libre phone working
with Verizon's network are practically nil.  If you truly wish your
phone to run 100% free software, then it would have to include the
baseband, and I am not aware of anyone who is working on any kind of
libre baseband implementation for the proprietary CDMA radio interface
used by Verizon, which is completely different from GSM.

And even if you would be satisfied with a phone that is only half-free
(free smartphone AP subsystem talking to a proprietary baseband) - to
me personally such a "half-free" state is of no value, no better than
having your teen daughter say "oh, no worries, I'm only half-pregnant"
- but I know others have different tastes - even such a "half-free"
state is unlikely to be attained on Verizon.  The reason is that
smartphones made for Verizon (with Verizon-compatible basebands) are
different in hardware terms from their standard GSM counterparts, and
the AP (application processor) part will almost certainly have some
differences too, even if they are gratuitous.  For example, Replicant
supports international GSM versions of Samsung Galaxy S2 and S3, but
there is no chance of it working on an SGS2 or SGS3 made for Verizon:
it's a totally different hardware beast.  Heck, even GSM versions of
these phones that were sold with USA carrier branding are not supported
because they are gratuitously different hardware, hence one has to
seek out and obtain an international version that is "not approved"
for USA (but works w/o approval).

Unless some miracle happens, the only way you'll ever be able to have
a 100% libre phone while remaining in USA would be if you switch from
Verizon to T-Mobile 2G, i.e., GSM.  If your current location within
USA does not have usable T-Mobile 2G coverage, then you may want to
consider relocating.  I personally use a cellphone with a baseband
chipset that only supports GSM/2G (still running the phone manuf's
original proprietary fw for now, but my own libre fw is expected to
become practically usable real soon now), I use T-Mobile as my SIM
card provider, and I get excellent coverage throughout Southern
California, from Los Angeles to San Diego.

HTH,
Mychaela

P.S. See www.freecalypso.org for more info regarding libre phones for
GSM that work with T-Mobile 2G.
