Heat the toilet pipe using a hair dryer or a paint stripper... do this from the toilet end and back in the basement as close as you can get to the cold water pipe feeding the toilet... metal pipes conduct heat nicely.
Be sure someone is holding the toilet supply tube into the bucket as you do this... shouldn't take too long to thaw!
Good luck!
