i did mine abotu 2 / 3 weeks ago. i thought i'd missed out on it as i had forgotten to do it 30 days after "purchase date". I i rang apple and they said that because i ordered online the purchase date was classed as the day i recieved it not the day i ordered it. so yeah nothing yet, but then again i don't check my bank very often so it may be there and i just havent realised 😛
