libqmi instead of NetworkManager?

Yeah, all that is true. I just assumed he was using a 3GPP+3GPP2 modem
in a 3GPP-only environment, and hence the warnings about CDMA
registration being unavailable. But yes, if it is not registered
either in one or the other, it won't allow to connect (at least when
using Simple.Connect()). A follow up email from Paul said that he
actually disconnected the antenna, so that's why he wasn't registered
anywhere! :)
