I don't think it will really be an issue. In the summer rebate program I submitted an invoice that didn't even have my name on it and it was accepted fine. (It was from the NokiaUSA four hour sale, and I wasn't able to order for myself at the time) Moreover, the form doesn't state that a receipt need be submitted, therefore I will not submit an invoice or receipt. Additionally, in my experience if one's rebate submission is declined, calling them always results in the rebate being sent, probably because they don't want to waste the time to figure out whether you're actually eligible. (Note, I'm not encouraging rebate fraud, I'm encouraging those whose phones are shipped after the 16th to claim the rebate for which they are eligible) Edited to add: I just checked, Amazon invoices clearly indicate the ship date..in much larger letters than the "order placed" date. Edited again to add:
