Okay so I have an iPhone 4 and the contacts are really frustrating me. For a few weeks I kept going to the keypad, entering a new phone number when I needed to, and then adding the contact from the keypad. After adding about 5 new people I realized that they weren't adding to my contact list. I can find them if scroll to the left and use the search iphone function. I figured out I have to go into contacts, click add new contact, and add it from there in order for it to be viewable. Why is that? My iPhone 3G never gave me problems like that.
