Samsung SCH-R355C ! How can I add a full street mailing address and other notes...

...to each contact? I have just bought the Samsung R355C handset as part of the "Straight Talk" prepay package. It seems that with the contacts, you can't add a street address for each contact or add any notes for each contact. Am I correct? Is there a way around this ?....I really want to add a street/mailing address and notes for each of my contacts like I had with my previous Nokia handset. Can anybody help?
