It is a good thing your application is not "real time" because then you would be violating the MP04 EULA. But you still have the problem that can't use handhelds with it either. Good thread on this topic at http://www.mp2kmag.com/mappoint/disc...pic.asp?t=3523. The relevent handheld posts are near the bottem.

If this is for a single application, you can also try www.dcs.com or www.it2me.com.

If you are planning to resell your product/service try www.geomicro.com and ask for the GeoLocator source code which is the client side application for iDEN phones.
