I haven't actually used a bluetooth receiver with the iphone but I've read
about what's required. First, you need a bluetooth receiver that's specified
as being compatable with the iPhone. There aren't too many of these as far
as I know and it means that all our receivers from the Symbian days are
completely useless. If you get a compatable receiver all you have to do is
connect it and the phone will use it, that's built in to the location
technology. This means that nothing special is required as far as any
programs that use gps go.
I don't know if this would give better accuracy or battery life. You'd be
trading use of the phone's GPS chip for the power required for a bluetooth
connection. In theory this should provide some battery saving but who knows
how much. I've found the phone's GPS to be quite accurate, at least as
accurate as my old iblue receiver. Even in the city it doesn't seem to
suffer from as much drift as the old receivers. Of course your milage will
very.

If so, which receivers would you recommend? How did you get
Loadstone or other programs to use data from a Bluetooth receiver
instead of the IPhone’s built-in chip?
Using the IPhone’s built-in GPS chip makes sense and works well for
most situations but there are two advantages to using a high-quality
Bluetooth receiver in my experience. First, the IPhone’s battery will
probably last longer. Second, Bluetooth receivers seem more accurate
in my experience. The IPhone’s receiver does not handle the urban
canyon effect very well compared to Bluetooth receivers, although it
does much better than either a Nokia N82 or N95.
