This question should be asked in the Windows Phone Answers Forum at the following address http://answers.microsoft.com/en-us/winphone/forum/wp6n Anyway, the only way to update a smartphone OS is installing a new and more recent ROM that will provide a newer version of the mobile operating system installed.
