I seem to have an i-phone sync problem too so wondered if anyone else has seen this or knows a fix?

Everytime I sync to my PC (running Windows XP) all my contacts get duplicated on the phone. Every single one appears twice :confused:

Additionally, from this morning, each time I use a contact to make a phone call it auto-deletes. So select it, make a call - is gone and has to be re-entered.

Thanks
