Have you tried activating it? If you havent, why not?
www.sprint.com/activate
Do it!
edit: wait a minute...first post you said you got it off of eaby, last post you said CL, and your profile says youre with ATT...do you even have a Sprint account yet? Something's fishy.
*cough*
Go activate it now and be done with it. If it doesnt activate, you got screwed.
