Everytime I try to sync contacts to my MBP or the PC I get this error that contacts can not be synced because of inconsistent data. It will push the contacts to my iPhone and touch but not to the mac or PC. I have tried the reset data to replace contacts on the computers but I still get this error. Thought it might be a glitch so waited till this morning and same thing happening again. All my contacts have disappeared from the address app on my mac. I have tried syncing contacts from my v1 iPhone but it just deletes them instead of sending them to the address book. Anyone any ideas please ????
