You can add prefixes (Dr, Mr, Mrs, Ms), suffixes (Jr, III), middle names, and other information to any iPhone contact. To do this, there’s a special option called Add Field. The option can be hard to find though. Here are instructions on how to find it and how to add prefixes, etc, to contacts:
1. Open the Contacts or Phone app:

2. Select a contact from the list by tapping his or her name once.
3. Tap Edit in the top right corner:

4. Scroll down through the tabs and select Add Field (it won’t be immediately visible. Scroll down by swiping upward):

5. You’ll see a list of fields. Tap any of the fields to add that type of information to your contact:

6. Enter text into the field and tap Save:

7. If you want to add more information, repeat steps 4-6. Otherwise, tap Done to finish:

And that’s it. Check out all our posts on iPhone Tips and iPhone Basics.

Thanks for the info, however, it seems to relate to the 3G not the 3GS.
As the article is undated at the beginning of the article you have to scroll to the bottom to find it is now a little dated. Can I recommend you put the date at the top, please.
I have found that adding extra fields can be tricky. Going back to the start of entering a new contact, if you add a name first to the ‘First Last’ fields (as against a company name), press Save and then go back and add the company name, the company name is unbolded. If you enter the company name at the same time as the person’s name, the company is bolded.
Likewise, it seems to me, but I haven’t fully figured it out yet, depending on the first information you enter in the ‘First Last’ fields causes the extra information fields to act differently.
It’s a great pity that Apple lets you struggle with this and experiment to find out what’s happening. You can waste a lot of time and effort entering information which you then have to delete and start again to make it look right.
I love my iPhone more than any mobile phone I have ever had [I'm Australian, we don't have cell phones] but I could cheerfully throw it at the Apple person who decided to keep most of the info on how to enter information a secret!

Thanks for the article… its all good and I discovered this a while ago myself, but what frustrates me is that if a contact has more than one/two mobile numbers your buggered and can seemingly only use One Mobile field on the iPhone. Any advice????
