Yeah, the Profile portion of the stock N9 Foursquare app seems to be sending "GET" requests for one or two components of the user profile information that are not allowed or recognized by the API.

If you acknowledge and dismiss the (many) errors, you will see your profile, but just with the invalid component request fields empty.

I would think that Nokia would be able to fix this pretty easily, but it does not seem to be on their radar...
