hamid, 14 Jun 2010do not have os?Hamid;
the meaning of OS is Operating System like windows mobile OS and Symbian OS... did you get my point my friend?
This Samsung M715 T*OMNIA II is a great phone but it doesn't have OS Windows Mobile and Samsung OMNIA II i8000 is much better comparing to this smartphone Samsung M715 T*OMNIA II bec. Samsung OMNIA II i8000 has OS Windows Mobile that is upgreadable to Winmo 6.5 and Winmo 6.5.3 and it has more features comparing to Samsung M715 T*OMNIA II, so my suggestion go for Samsung OMNIA II i8000... Thank you
