MMCPwd allowes you to restore your lost MMC password. Its very small program (only 6kb), and it has guaranteed sucess. Program displayes contents of the mmcstore file where the password is hidden.
Program is only for Series 60 smartphones. It has been tested on N7610 and N6600.

MMC password can only be retrieved on the phone where the password was set. If your phone has been formated after the password was set, there is no way to retrieve password.

This is my small contribution to Symbian community
