iPhone: Any Questions? Here Are the Answers

Apple published a "Questions and Answers" webpage online. It provides additional details such as the preinstalled SIM, even though it is not stated if one can exchange it or not. One can also view PDF, Microsoft Word, and Microsoft Excel email attachments in their original formats. However one can not unlock the iPhone as AT&T is the exclusive wireless carrier, and users will have to transfer their number when activating their AT&T account. It remains unclear if this will remain true in 2 years (the required subscription period).
