Forget OVI manager, computer connection or OTA sync.
The easiest way to migrate your contacts list from S60 to android is by select all contacts (from the S60 contacts menu) and copying them to memory card.
After that eject the microSD from S60 and pluged in your Android device. Go to android contacts menu and select to import all contact files founded in memory card.
———–
If your S60 does not have memory card but only internal massive memory (N97, N95 etc.) after the copying contacts to massive memory, go to ‘other’ forder from file manager, select all .cvs files and send them via bluetooth to your android device. After select search and import contacts from android’s microSD.
