So I have made my own plugin. I've seen a few forums with people who want to get their Nokia 5130 to work with isync.
The plugin should be put into /Library/PhonePlugins/
If the folder doesn't exist create it.
This probably only works on snow leopard (10.6). You could try 10.5 but no promises.

Enjoy!
UPDATE (13/12/2009):
It seems the birthday and photo fields can cause some problems. My phone has contacts that would sync fine one time and not the next.
I have tried to fix this but can't se what is wrong, especially as it changes each time i sync. Strange.
So what I have done is prepare 3 versions of the plugin (this time with installers, so no confusion over which to use).
Full Version:
Includes all contact details that the phone supports
Download Here
Normal Version:
Excludes Birthday and Photo fields
Download Here
Basic version:
Only has email and phone numbers
Download Here
Let me know in comments which version works for you. I use the normal version, because the full version works sometimes, but frustratingly not all the time.
UPDATE (23/03/2010):
Unfortunately this is no longer working for me and i have no idea why. Great that some of you have had some luck. Apologies to the rest of you. I have tries to fix it but have decided it must be a problem with the phone (maybe the reason it wasn't supported in the first place). I'll keep try to get it working but dont know how much luck i'll have.
Hopefully it still works for you!
