How do I reset the phone to factory settings?

EDIT
Okay nevermind I'm stupid...
I found my answer.

Sorry if this has been covered before.
If it was I must suck at searching, forgive me.

So this is my first Android phone and now that I've messed around with it for the past 2 days I'd like to start over clean.

So how do I reset the phone back to factory settings?
And will I lose any of the preinstalled programs?

Thanks!

yes you will lose them but everything that is market/contact is attatched to your gmail name

Steps to hard reset Android:
1. Go to “Setting”.
2. Select “SD card & phone storage”.
3. Select “Factory data reset” which should be the last option.
4. Press the “Reset Phone” button.
