I have to transfer all data from 7650 into 6230 (phone book, SMS and calendar as a must).

A. Using PC Suite is impossible since those phones use completly other software and backup files are not compatible.

B. Transfer through PIM (e.g. Outlook) is not working with SMS at all, not mentioning other usefull files (sounds, pictures)

What tools I should use? How to retrieve data from backup files on other phone type then the one used to store data?
