This deleted half my contact from google and thunderbird.
I re-created all the contacts and a month later, it did the same thing.
Do not use this
Sorry it didn't work for you. Could you try to recreate this and send me a log? Make sure your computer's timezone is correct and that its clock is synchronized.
gContactSync ALWAYS asks for permission before deleting more than 5 contacts so if this every happens to anyone click OK to disable the address book and send me a log.
