dougeeebear, I don't think that's the aim. The original poster has the same question as myself: Is anyone having experimented with these CF cellphones. The idea is to turn the Z into a cellphone, not connect it to a separate cellphone. We want to reduce the Batman factor by one (removing one of these devices in your belt) and increase the Bond factor, by integrating one more device into an existing one.
Hope this clarify.
However, if your own setup is not yet documented in the howtos, I strongly encourage you to document it and submit a document to integrate in the HOWTOs. For sure, it will help somebody else.
