Bluetooth means never having to plug in a cable when synchronizing your phone or PDA with your Mac.
Apple’s iSync, the synchronization software based on the SyncML protocol (http://www.syncml.org/), synchronizes the contact and calendar information on your mobile devices with your Macintosh. In addition, if you have more than one Mac, it will also help to synchronize the information in your Address Book and iCal calendars (.Mac (http://www.mac.com/) membership is required).
The mobile devices supported by iSync include the latest GPRS, Bluetooth-enabled (http://www.apple.com/bluetooth/) phones (such as the popular Ericsson T68 and the Sony Ericsson T68i) and Palm OS devices (such as the Palm m515). iSync even synchronizes the information on your iPod with your Mac.
To download iSync, go to http://www.apple.com/isync/. The download is about 7MB. You need to have the latest Mac OS X 10.2 Jaguar running.
Installing iSync is a snap, provided you already have iCal installed. iCal is required for iSync to work. You can download a free copy of iCal from http://www.apple.com/iCal/.
iSync contains two packages: iSync and iSync_Palm. The latter is required for synchronization with Palm devices.
For this hack, I have tried iSync using my Ericsson T68 and my Palm m515. I will walk you through the steps to get the devices connected as well as to set up Bluetooth on your Mac so that the synchronization can be done wirelessly.
