Using iSync with Bluetooth Phone and iPod

[fryke]

Just an addition: There are also phones that are similar to those listed on the page linked by texanpenguin. For example, you might get many Series 60 phones to work by hacking around iSync's code a little (look at the link about the 9500 in my sig, that might give you an idea, it's rather easy).
From my experience, Symbian based phones that _should_ work with iSync (because they share the same features for synching as supported phones) tend to _be_ supported either through Apple or some third party hack you can find at macosxhints.com or a forum about the particular phone.
