The ruling (Rulemaking Proceedings Under Section 1201 of Title 17 | U.S. Copyright Office, part (2)) is specific to "wireless telephone handsets", which the iPad is not. The press reported it incorrectly as "iPhones and other mobile devices", but it is narrower than that.
Well as the iPad also now has facetime, the new one at least could probably fit into that ruling.
That would arguably make it a "wireless telephone", but no mere functional change could make it a "handset".
