Itunes no longer synching to Windows Contacts
Sorry for bothering you guys. I'm a bit desperate.
I have an iPhone 3s and I've been synching the contacts to Windows Contacts (Windows 7) for about 10 months without trouble.
Lately (2 weeks ago) I found that Itunes no longer synched the contacts, because new contacts added to the phone did not appear in Windows Contacts. I have the latest Itunes version and I have made sure that the box "Synch with Windows Contacts" is checked.
I have also reset synch history as suggested by Apple's web site.
As far as I can tell, the only thing that could have caused it is that I transferred all the contacts to a Sony Xperia (my wife's phone) via Sony's PC Companion, about 2 months ago. But whatever may have caused it, I still don't know how to solve the problem.
Thank you all in advance.
