Samsung will release a phone that uses Nokia’s Series 60 user interface. Some handset manufacturers have licensed more than one OS. Samsung has licensed OSes from all three major makers: Symbian, Palm, and Microsoft. A ZDNet article and and PC World article have more. Update: A PC World article reports that the first Microsoft powered smart phone has been launched by European carrier Orange SA. AT&T will be the first US-based company offering a Microsoft-powered phone, in mid 2003.
