I have a PB G4 667Mhz 256MB OSX 10.2.6 and a Motorola V60i(T) on ATT TDMA network. I found a third party USB data cable. iSync and the Network control panel both recognize my V60. iSync is only syncing 20-30% of the contacts in my address book. So currently my v60 has a subset of all the contacts in my address book(~90 contact ~120 phone numbers). The v60 says it has lots of free memory.
