I've been noticing the the INQ1 launch in the UK which is the first example of an operator launching a social networking phone. It's a white-labelled service powered by SEVEN (interesting how the email providers are all migrating to the social address book as a messaging platform, but that is another story). Hutch has done a great job of bundling it with a special rate plan and clearly targeting the service.
Supposedly there are 50,000 pre-registrations for the phone. Will this take off? If it does will it signal a new migration to operators optimizing devices and web services for specific customer segments?
After RIM and Apple have been eating market share from handset vendors (especially Nokia and Motorola) and Operating System platforms (Windows Mobile and to a lesser extent Symbian) it would be very interesting if this model was adopted successfully by operators as opposed to device vendors.
