Under settings, click language & keyboard and see if Swype is there. If it is make sure it is checked, and then it should be selectable if you long press in a text field and hit input method. If it is not in the keyboard menu then it didn't come with your ROM. Either way, head to beta.swype.com and sign up for the beta program. Once accepted you will never be without, just keep the installer apk they give you on your SD card and you can use it in any rom.
Thanks. I actually got the answer from venemus @ XDA and am posting to share just in case anyone else has similar question. "Long press on anywhere you can type something. Then select input method>select swype."
