Apple just started canceling iPad 2 orders in the U.S. that ship to freight forwarding services or international addresses. This is the email you receive from Apple if you try to order an iPad 2 via nybox.com:
Dear Apple Customer,
Thank you for your recent Apple order.
While we appreciate your interest in iPad 2 and iPad 2 accessories, we
are unable to process your order. Apple is unable to fulfill orders
that exceed the quantity limit per customer, or that ship to an
international, freight forwarder, or an APO/AFO address.
Your iPad 2 order has been cancelled, and you will not be charged.
Apple Online Store Team
It seems only iPad 2 orders are affected, Apple store orders shipping to freight forwarders for accessories like JAM by Apogee are still active.
