The most important question is whether it can work as a daily phone,

in this respect.
As far as i can say from early testing, the sound quality is good. I
still
need low latency software for routing the sound between UMTS and
speakers, but
otherwise the modem seems to work reliably - i have been receiving
SMS and
calls without any issues.
This issue should be solved with the next board version GTA04A4 which
is produced right now. This board version connects the modem directly to
the TPS chip which contains all the sound related stuff. Therefore it
should work without additional software if you adjust the right alsa
switches to route the audio between modem and mic/speakers.
So with good power management this has potential to be usable phone.
This is still to do. The OMAP platform is very capable of saving power
but everything must be set up within the linux kernel. This is a
challenging task if you didn't do this before. I'm still trying to
understand all necessary bits to help out here.
