I haven’t used a non-Windows Mobile phone in years. However, the last Nokia I tried was the venerable 3650 (a Series 60 phone) and I liked it a lot during the time I used it. So, the combination of my interest in the new Nokia N95 and John’s comment about Nokia sync support on Macs being poor gave me pause for thought. I still don’t have a definitive answer. However, I did find that Nokia posted what looks like iSync plug-ins for use with some of their newer phones with Macs linked below.
Nokia – iSync

If anyone has experience using this Mac plug-ins with the targeted Nokia phones, please let us know how they worked for you.
