What about tagging your prefixes as no-export instead of withdrawing 
them entirely?  You'll still get traffic from Sprint and it's customers, 
but that's significantly less than you would if they were announcing 
your prefixes to their peers.  It may be a good compromise.

If memory serves, sprint honors no-export, or recognizes some other 
community that accomplishes the same thing.
