I am confused. Assume you have a Nokia GPS enabled phone.
Does the phone capture the track data and then you must upload to a site?
Or does the phone somehow communicate with the Nokia server, capturing GPS tracks?
And if this it the case, don’t you need a data plan with a carrier?
Finally, how often is the GPS data captured?

I’m trying it out with my Garmin Forerunner 301 as you can import .GPX files. It looks pretty good, and the live event tracking and geocoded photo uploads allow for some really interesting possibilities.

Hmm, I don’t think you need a E-series device specifically, but any new S60 (3rd edition) device should do as long as you have got a Bluetooth or interated GPS and Internet connection.

For example, my 6120 Classic is capable of running sports tracker with my Bluetooth GPS. And, the N95 should still be capable of running it.
