The readability argument doesn't really sell me, but the consistency one does:

Python 3.2:
>>> iter(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>> next(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: int object is not an iterator

We generally do quote the type names in error messages, so this change
is just bringing next() into line with other operations:

>>> 1 + ''
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'int' and 'str'

Cheers,
Nick.
