Great question.

When you think that very soon people will be able to order Xohm N810 Wimax´s or of the new capablities with Maemo 5 this will become more interesting.

All I know is also the Nokia N95 has a mini-USB B socket, but by using the PC Suite software it can be transformed into an OTA Phone modem.

I personally wonder what the theoretical max. speed would be when using this interface.
