A caveat: @selop just said at #MWC11 that Nokia plans to start making money with ads. That's called a service, but I call bs. Stats have shown that ad revenue is not where it was expected to be at this point, and not only that, ad providers still don't get how to get ads to potential consumers in a nonobstructive way. Ad placement in games can be fine (eg, click on a billboard in Grand Theft Auto) but unfortunately providers seem to be stuck in this "put the ads in the page body/lobby/etc".
