I remember using the IR port on the 5mx (I think the 5 had this but I'm not 100% sure) to talk to my phone at the time and use it as a modem while on the move.

I remember using the IR port on the 5mx (I think the 5 had this but I'm not 100% sure) to talk to my phone at the time and use it as a modem while on the move. It was hardly convenient, but it worked. Not fast or cheap either, IIRC limited to 19k200 and paying by the minute at hideous mobile rates.
