In any case, it may be worth noting that the manual says correlated subqueries "are inefficient and likely to be slow. Rewriting the query as a join might improve performance." <http://www.mysql.com/doc/en/Correlated_subqueries.html>.
SELECT person.pid, count(*) AS C FROM person, phone WHERE person.pid=phone.pid GROUP BY person.pid;
+------+---+ | pid | C | +------+---+ | 1 | 2 | | 2 | 1 | +------+---+ 2 rows in set (0.00 sec)
