Last week I got a new Motorola v323i phone from US Cellular (which blows my old LG out of the water). I wanted just a basic phone with bluetooth and decent reception so I could sync it with my iMac. Unfortunately, it doesn't just work out of the box since iSync doesn't support the phone.
After a little research, I found this reference on how to write your own phone plugin. I also found this guy's site where he had already written a plugin for a v325 (basically the same phone).
So with a little tweaking, I made my own v323i plugin. To use this, unzip to your Library\PhonePlugins folder. You might have to create the PhonePlugins folder if it doesn't exist. Then add your phone as a bluetooth device, and if all goes well, you should then be able to add it in iSync.
Right now, I haven't built in USB support so it's bluetooth only. Also, for some reason the phone icon doesn't work, but it will sync your contacts and calendar. Feel free to shoot any questions or problems my way...or if you know of a better place for file hosting.
