Mike,
Is that what the BT profile is about? I thought it was just to have a
standardized handsfree calling built into the car. How do the accomodate for
all the different cellular standards (e.g. CDMA, TDMA, GSM, iDEN, etc)?

Interesting, but not really where I wanted to go.

What I actually want to do is drop my POTS service, and use a
Cellsocket adapter to enable my home phones. I was hoping to find a
way to avoid having to switch the SIM out of my Treo (which won't work
with the Cellsocket) into a Nokia model every time I come and go.

Yeah, but it was $20/month for the service!  SBMS called it "flexphone"- it
was designed for people who wanted to use both a 3-watt car phone and a
handheld on the same number.  You didn't have to use it that way, but it's
restrictions made it little good for anything else- only one phone could be
on at a time (if you turned both on, only the first one switched on would
work), and only one phone (whichever you designated) would be capable
of roaming.

When TDMA service and digital phones arrived at SBMS it was the
beginning of the end for flexphone.  Official policy was that flexing was
only for analog phones, but exceptions were occasionally made for folks
who upgraded to a digital phone yet lived in very weak signal areas.  
By the time "Cingular" was born, flexphone was pretty much dead and
buried- by that time "family plans" had arrived, and allowed you to have
two phones on one account cheaper than flexphone, without the "one
phone on at a time" restrictions.

Which leads us logically to the next point- perhaps the OP could
consider a "family plan" for his Treo and Nokia phones.  It might cost a
little more, but he'd have the flexibity of still having a working phone at
home when he's out, and with conditional forwarding, could forward
calls from his mobile mobile to his home mobile when he's not, er, mobile!

That's what I did when I went landline-less.  I added a family plan line
to leave cradled at home in a cellsocket as I don't live alone and didn't
want to strand the family without phone service!  (My wife has a mobile
as well, but it never leaves the car, lest she forget to put it back and
negate the safety aspect we mainly bought it for.)  The $20/month we
paid for the family plan was still cheaper than the $40+ we paid for
rural POTS.
