Microsoft has shared more information about Windows Phone 6.5 Starter Edition and it sounds slightly more useful than Windows 7 starter for the PC i.e. not useful at all.
From ZDNet- “Neowin first reported over a week ago that Microsoft was planning a Starter version of its mobile operating system. But that news was overshadowed by all the Windows Phone 7 Series hoopla from the Mobile World Congress in Barcelona.
Windows Phone Starter is similar in concept to the original Windows Starter Edition products. Windows XP and Windows Vista Starter were products exclusively tailored for emerging markets. With Windows 7, Microsoft broadened the availability of the Starter Edition to include all countries, with Home Basic becoming the new emerging-market-only SKU. So far, it seems as though Phone Starter is going to be an emerging-market play only and not a low-end platform for users in developed countries.
As Neowin noted, Windows Phone Starter will be available in two versions (one with Office Mobile and one without).”
