How to delete text contacts from LG Rumor Touch?

I left my iphone at my brothers home and now he is out of the country until mid december so I decided to reactivate my old LG Rumor Touch. Actually I really like the simplicity and its' small size but I digress. I have dozens of text contacts loaded on the phone most of whom I have no idea who they are. Anybody out there know how to delete texting contacts. Regular phone contacts are not a problem and are quite easy to change but I can't seem to get rid of unwanted text phone numbers.
