Like 4mee said, it doesn't since its a hybrid phone, meaning it uses both the iden for nextel and cdma for sprint (that's what the ic stands for) so it has to use a standard UI. The i930 uses windows mobile 2003, not to sure if it can change to windows mobile 5 or 6.
I have the IC902... If you have any questions on specifics about the phone or would like more information, just let me know!
