GMM is Google Maps Mobile. I know I can get it on my phone... I'm looking for an app like GMM that offers a service like Latitude because for some reason EVERYTHING else will work with my new GPS puck except GMM (Except 2.2.2 which works perfect but does not have Latitude).
I thought you might have been referring to Garmin mobile maps. Anyway, there's nothing else like Latitude out that I know of. You might want to check the GPS forum down the list.
