Trimble outdoors makes one too, but they have not answered my questions as of yet.
I got a reply from Trimble saying that their software is not supported on smartphones like treo or blackberry 8800, but they would like to port their software to those devices ... however, they could not give a timeline for that.
I also contacted the makers of SPOT asking if they were maybe making software like Trimble, particularly AllSport GPS, as I heard rumors on other threads of that happening. At first they replied "a very interesting approach! Could you please tell us more on what exact features you are thinking of?", and when I described the idea of odometer, speed, elevation etc., and pointed them to AllSport GPS website, they replied "thanks a lot for your input. To be honest, we are sort before rolling out a new application. Please keep an eye on our website.
So there you have it ... keep an eye on their website
