Is Sprint Nextel supporting Abortion-on-Demand?

I was recently forwarded this information that a group called Working Assets Wireless is allowing you to sign-up for a wireless plan that gives proceeds to Planned Parenthood, the single-most vocal supporter of abortion-on-demand (without apology) in America. Working Assets Wireless, a company from Mechanicsburg, Pennsylvania, may just be some local outfit owned by pro-abortion advocates trying to whip up cash for their financially-strapped charity, but I really question the involvement of Sprint Nextel Communications in this cesspool.
