Apple some weeks back released 10.4.9 of OS X and with it, iSync version 2.4.

At the time, I failed to notice that the Nokia 6131, which is the Euro/Asia version of the Nokia 6126 that I have, gained support in the new iSync.

Mainly, my addresses are now synced into the address field as they should, and not into the notes field! Woo Hoo! Tiny little things that really make your day.
