Why Android 4.2 phones won't have multi-user login? Hint: Nokia holds the patent

A mobile telephone is designed to be used by several different end-users at different times. A first end-user can alter the mobile telephone so that it operates in a manner specific to that first end-user and a subsequent end-user can alter the mobile telephone so that it operates in a manner specific to that subsequent end-user; wherein each end-user has only to respond to prompts displayed on a screen in order to alter the mobile telephone so that it operates in a manner specific to that end-user...

The present invention therefore moves away from the established assumption that a mobile telephone is personal to a single end-user and instead readily allows the mobile telephone to be used by several end-users through appropriate on-screen prompts. Such a device may be especially relevant to communities where few individuals can afford the cost of their own personal telephone. More generally, it is useful for any entity to whom there are benefits from being able to easily share mobile telephones across multiple end-users (e.g. large corporation may have a pool of such mobile telephones; any employee can then simply pick up one of these telephones and be able to use it like a personal device).
