Is Microsoft looking to take a leaf out of the iPhone's book? There is nothing in the press release that dropped into my inbox to suggest that this may be a new service for Windows Mobile, but I wouldn't be at all surprised if that's what happens.

Web based maps like Multimap or Streetmap are very useful, although of course without GPS you have to have some idea of where you are.

Having a quick look at Multimap, I quite like the Wikipedia add-on showing points of interest, including one of our favourite restaurants, Yauatcha.
