I access the Ovi Contacts tab in the contacts application.
Select Options > My profile
Change First name and Last name.
Press Done.
This is not updated to people that I am linked to in their view.
In the My Profile view, the top line still states Anonymous. Under this is my Ovi account email address.
If I then sign off, exit contacts, and reopen the app, returning to My Profile, the data I have input is not there.
