Clearing Txt message history?

I got the phone 2 weeks ago. I did not see the clear history button. So I am assuming I am not live in Froyo-ville or else I am just too new to this phone to know. After all, it DID take me about a half dozen calls to figure out how I am able hang up on my own.
For any who havent figured this out yet...

1) Tap Contacts button

2) Scroll to Contact where Text History is showing up

3) Drag the Contact Details screen 1 1 screen to the right to open the History Screen

4) On the History Screen, click the Menu hard button, and then click Clear History.

5) This if done correctly should clear all calls and messages retained in the contact history.
