How do I insert emoticons in my phone for text messaging?

It's a motorola rokr, and it came with some little emoticons in the media under 'pictures' already. I cannot insert them in texting messages, but others can send me the same emoticon in their texts to me. What is going on with that? Thank you.|||Try to go write out a text message and look to see if there is options. Select that and then look in there to insert an emotion. On my phone is it this: Write out a text--%26gt;Options--%26gt;Add--%26gt;Animation
