Why does it say the phone is unlocked, yet requires you to tie your device to an account before ordering? As an example, I don't have a separate AT&T account, as my phone is tied to a corporate account. Obviously my company is not going to release the billing information for the corporate account, thus I cannot order a phone through the AUP. Seems flawed in advertising, in that you can't just order the phone and make payments, without being tied to a carrier before ordering. Am I missing something? Are in-store options different, in that I could 'buy' the phone under the AUP, without providing wireless account details, and bring my own, functioning, AT&T sim?
