custom firmware if we purchase bulk volumes of phones, but the
modifications they will do may do only part of what is needed. Either
way the rest the technicians can do anyway. They'll get back to me soon
with details. Regardless of the outcome we've successfully probed the
hardware and can definitely do the required modifications ourselves for
one of the suitable phones, although it would be better if we get the
manufacturer to some of the mods for us. But in addition to firmware,
extra hardware needs to be used, then integration of it all which is a
very fiddly job.
It may end up meaning there will be enough phones to last years, which
is more than needed. But if that's the case, they'll be used for the
lite and uber computers.
