How do you make corrections in the contact list once it is saved?
In your Contacts, tap the square where the phone of the contact should be in, info about the contact will pop-up, tap the top part of the pop-up (area where the contact's photo should be). Should then see that one contact alone with all info of him/her. Press menu key, choose Edit.
Hope that helps! Let me know if you were able to do it. :)
