It'd be interesting to know whether this is uplink-only, like most devices of the Spot series of devices on Globalstar, or whether the iPhone can also receive acknowledgements from the satellite.
As far as I understand, Globalstar's downlink capacity is (or at least was) severely limited and also uses a different frequency band than their uplink.
