For its part, Nokia doesn't appear interested in entering such a business itself - essentially it sees the deal as a way of building demand for its handsets. With almost all phones bought by mobile networks and sold on to subscribers, Nokia's key customers are not consumers but networks. If it can put them in the way of a service that has real customer appeal and - crucially - encourages users to make use of their data-oriented networks, almost certainly 3G ones, then hopefully they'll buy more handsets from Nokia.
