This is a post of warning for people thinking of setting up Google Sync on their iphone. I have just done it and it has copied every single email address i have ever sent an email to onto my phone. I now have 1000 contacts instead of my usual 250. Also (at the moment) google doesn't acknowledge more than one mobile phone number so every contact that had more than one mobile phone contact has been deleted, I now have to enter them manually from Address Book on my mac which has them all backed up. Once I have deleted all the contacts I don't need it will be a really good service, it's just the pain of having to do it now!!!
