Contacts didn't work under IOS 6

Hi, I have a Prop with my IPhone 3GS with IOS6, Calendar sync works fine, but Contacts didn’t find any connection.
Desktop, Android, IPad, all Divices working fine.
Under owncloud it was working, does anybody know whats wrong?


AFAIK Apple’s Carddav implementation was buggy at some point, I guess it’s fixed in newer versions. Unsure if anyone can help you with such an old phone however.
