Hell freezing over humorously referred to the fact that Apple had finally developed a major consumer application (iTunes) for the Windows platform.
In recent weeks, Apple's site has seen a few changes due to the release of iBooks and Mac OS X Panther, but their 'Introducing iTunes for Window' splash page now removes the amusing 'Hell 'reference.
We received a report that the reason for this is due to the objection of some higher level individuals who were involved in the Richmond, VA school system iBook purchase (23,000). Due to this (high profile) objection, Apple reportedly changed their page to remove the reference.
Update: Reportedly, the schools had actually blocked Apple's domain during this time.
