Yeah, all I want with this one is SMS access.  You've got both receiving
and sending working then?

I don't seem to have a null modem cable on hand, but I'm sure I can find
one around somewhere, or at least borrow one from a friend.  Thanks for
the suggestion.

It looks intentional, actually - the seventh connector (counting left to
right where the cable plugs in) actually has a slightly different length
hole in the plastic casing.  The cable definitely has 7 pins though. 
The seventh connector on the phone looks exactly like the two either
side of the charger socket.  What does yours look like (or has that bit
been soldered over)?

Now that would be nice, much though I dislike non-deterministic results!
