i would think and this is just my brain thinking that you would have to wait until at least we see the symbian 3 device appear

this new device may be running a new version of maps that will be built in qt or it may still even have the older symbian maps on it

symbian supports qt and iam sure the new device will have a version of maps avalible either symbian or qt

qt will be hitting laptops , mobiles , car entertainment , it makes sense to have a nokia maps version in qt to hit all them devices :-) but how long before we see it is another thing

i think it will be a little while yet to you see a better version of nokia maps for the n900 lets put it that way :-)

why not go for sygic
