Even if your mobile phone is not listed in "iSync: Supported mobile phones in Mac OS X v10.4, 10.5," you may still be able to synchronize it with your Mac.
Several third-party vendors (both handset manufacturers and independent software developers) provide iSync mobile phone and mobile device plug-ins for Mac OS X v10.4 and 10.5 beyond those provided in Mac OS X itself.
Please see below for lists of vendors who support different devices. Note that certain plug-ins may only work on more recent versions of Mac OS X.
Important: The information below reflects many third-party plug-ins developed for use with iSync. We have attempted to ensure this list is accurate as of its noted date, however it is subject to change at any time. Due to the wide range of mobile phone devices that may vary widely in their capabilities, the many different ways manufacturers implement and may change implementations of their devices, and, the complexity and uniqueness of any given operating environment--you should use this information only as a general guide. The accuracy of this information is not guaranteed by Apple; and users of this list must assume responsibility for purchase decisions. The purchase price of any third-party plug-in is decided solely by the developer and not Apple.
