There was a bit of confusion with Apple's online store update yesterday as to when the 3G version of its iPad will actually make its retail debut. Let that fog of ignorance be no more, as Cupertino has today named April 30th, a Friday, as the day the WiFi + 3G slate will arrive in stores. In American stores, that is, don't get all excited if you live outside the 50 states. That's also the date when early pre-orders will be fulfilled. Deliveries for those were promised for "late April," though clearly this date has more of the late and less of the April to it.
