Hi,
Those femtocells use ipsec to which the keys are not available (yet). The ones that were
not automatically upgraded by Vodafone and therefore expose a serial shell might be used,
but that requires some more investigation (and sadly not much of un-upgraded versions
exists...also downgrading isn't an option if I'm correct because they do this
inside the IPsec tunnel).
Maybe Kevin has more memories about them :).
Other femtocells (e.g. SFR) that use EAP-SIM should be easily connected to an open core
network by simply using SIM cards with known keys.
Cheers,
Domi

Does anybody know if it would be possible to use some
of the old vodaphone-femtocells together with openbsc/osmo-bts?

Short answer: no & no
1 - A gsm repeater is an analog device. With osmocom-bb phones you would need to
demodulate/remodulate bursts.
This will mess with timing advance, and you won't be able to send bursts in the same
frame/timeslot they were received.
2 - Calypso don't/won't support 3G.

The place where I normally play with osmocom-bb has pretty bad 2G coverage and I was
wondering if I could make a signal booster/repeater with a couple of osmocom phones?
Also wondering if 3G would require totally different hardware than the old Calypso
motorola phones or if it could be achieved with firmware+DSP changes?
I have a 3G cell spot that boost that signal so just trying to find a way to make an
osmocom-bb phone work well in my place.
Thanks,
