Cell Phone Syncing w/ Your PC or PDA?

IPSection asks: "I have been looking for a way to sync my PDA or Outlook to my cell phone (a Panasonic EBTX210). The serial data cable didn't come with any software (of course) and the only commercial solution I see is software called FoneSynch from Paragon Software (Windows only). Is there any free/shareware software for Windows/Linux that allows this functionality? Come on all you cell phone users - don't tell me you type in all of those numbers manually?" We've handled this question in a couple of earlier articles before, however there doesn't seem to be an all-in-one utility that once can use to extract your messages/address-book from your phone (or to allow you to set your phone from your PIM, for example). Many utilities focus on a specific line of phones (like Gnokii, which only works on Nokia phones) and others only work if your phone supports GSM or CPDP. If no all-in-one solution exists, what utilities have you found useful in keeping it all together?
