Interesting. Maybe it's whatever certain APIs are exposed to the mobile Bing app? Clearly, the web version has some kind of auto correction the mobile version doesn't/can't access.
Btw, how come you didn't question why it was placing the marker on the green side of a mountain?
That is a shame that Microsoft's own secrutity retrictions on API's is making Bing Maps crap. MS needs to get off of it's high horse and stop retricting the phone so much and then maybe they will sale more. I'm still not happy with the fact that you have to listen and tap for the next instructions on it agg even my old crappy WM6.0 had a better map navigation than this.
