Actually you can do it quite easily if you have access to your sprint account page on sprints website.

If you do, log on, choose your phone from your account list (if multiple phones are on the account) and choose preferences.

From there you will see the choices to block calls, texts, data, etc. You can block individual numbers for both calls and texts.

Hope that helps. Works for me. I'm blocking my son's ex girlfriend.... heh heh heh

EDIT: you can also do it by sending a text to sprint with the number but I'll have to look up how to do that and I'll post back.

EDIT 2: OK, to block texts, you text to 9999 and key in BLOCK and the 10 digit phone number.
