I have a Nokia 6230 myself and it doesn't work w/ iSync. It's not a Series 60 phone (Symbian), it's Series 40 phone. Go to versiontracker.com and look for a program called PhoneDirector (
http://www.versiontracker.com/dyn/moreinfo/macosx/23570), it's a program that will sync your Nokia 6230 w/ your Apple via Bluetooth. You can try it for free and purchase the full version if you like it ($29.95). I haven't purchased the full version just yet but it works fine.
Anyway, while we're talking about the Nokia 6230 phone, I'd like to say it's a great phone although it doesn't look cool like SE phones. It has a ton of features like vga camera, video camera, mp3 player, FM Radio player, bluetooth, infra-red, speakerphone, voice recorder, etc... Also it has an included 32 mb external mmc card which you can upgrade up to 1GB, Newegg has one for $75 (
