Peter,

Thomas, are you aware of any service which can be used for airborne
data - other than the full TCP/IP thing from say Iridium?

Inmarsat offers a service, I think. Connexion by Boeing works with
Inmarsat, too. And Iridium, as you say.

I believe there is a data service run by Ericsson, on the back of
their GSM network or something like that.

GSM wouldn't work. The antennas don't receive from higher altitudes
(above, say, 3000 feet).
