OK, for everyone keeping score I can only get this working in a browser. As others have experienced, Maps keeps asking me to login or, if logged in, Latitude doesn't seem to work at all.
I had Latitude working somewhat on my kyros. I had to use an app called My Fake Location and set a location to get maps to not FC. Once I did that, I had latitude working though my position was always fixed. Trying to get the app to load on my Nook but I cannot get it to install.
