Despite postings on the code.google forums I've had no luck with this yet.
I have an app on my WM5 device which stores lat/long data. What I'd love to be able to do is to pass one over to google maps mobile and have it show the location graphically. So far I've had no luck. I have to copy the lat/long to the clipboard then paste it into the seach box in GMM - not very elegant.
Anyone got a result on this please?
