A Microsoft job advertisement revealed that Windows Mobile team’ll not only support the layer of custom interfaces on most Windows Phones today at an OEM level but’ll even help create custom interfaces for individual operators comes Windows Mobile 7: “The final responsibility of our group will be working with mobile operators to deliver a unique windows mobile experience that seamlessly integrates the mobile operator’s services (such as voicemail services, video-on-demand services, and navigation services for instance). Microsoft experimented with this back in 2007 with the introduction of the T-Mobile Shadow. That was a great success and with WM7 we will be expanding this effort to more operators. Because of this we will be working heavily on creating custom user interfaces, so passion around UI and graphics programming is a must,” noted.
