What tools would a plumber use to clear a jam in the toilet?

Suppose a girl drops her iPhone into the toilet, and it happens to have waste in it. She thinks it's so gross to reach into the toilet and the phone wouldn't work anymore anyway, so she flushes the toilet. A day or two later, the toilet won't flush properly due to a jammed up drain line caused by the iPhone, so she calls a plumber. What kind of equipment/tools would he use to correct this problem? How much would it likely cost?
