Hello all, hope someone can help. I have about a hundred contacts in my address book on my mac and have been using mobile me to sync them with my iPhone. Until a few days ago all was working fine but in the last few days several of my contacts seem to be duplicating themselves at random. There are about 250 extra copies of about 15 or so contacts. I used the 'check for duplicates' function in address book to reduce them back down but no matter what I do, the contacts list in mobile me wont accept the changes, and therefore niether will my phone. I even went through them one by one in mobile me on the web and deleted the extras manualy but the phone wouldn't sync and two hours later they were all back in mobile me. It's getting me down, (I did'nt realise I was this fastidious.) At this point I am willing to start again from scratch using my back up address book, but I'm scared that these errant duplicates will appear from somewhere and wreek yet more havoc on my lovely clean system.
