I am assuming this is not the 3g model and includes offers unless told otherwise. Can you post the entire serial number to confirm this unit can be registered with Amazon? The number can be found on the box, bottom back of the unit, or on settings page and is 16 digits.
I have returned this unit to factory specs by de-registering it. It certainly can be registered with Amazon. However; this can be done w/out the unit and only the serial number. If I give out that number online, anyone could register this unit and thus making it inoperable for anyone who bought it. You are correct. it is not the 3g model and does have special offers.
