How do you check deleted messages on the Samsung Eternity?

I left my phone at my friends house and I think she sent my friends some texts. I want to see what they said. PLEASE HELP! I have the Samsung Eternity! I want to see the erased SENT messages and the erased INBOX messages for text messaging! Thanks in advance! :)|||I don't believe that's possible once they are deleted they are gone. You can view your account online and look at the numbers that your phone sent and received messages from. That's all i think you can do.
