There's all kind of stuff in TOU's that the lawyers insist on. I think Apple are actually concerned that people will run telephony apps across the mobile network. So the threat isn't in the language/environment per se, it's the apps they might support. Presumably a delinquent app can be identified by its traffic and the iPhone disabled whatever language is used.
