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,Craig
