This is strange. I got my new iphone with micro sim, did the swap procedure online, and it sent the 6 digit authorisation code to my NEW sim card. Is that right? My new sim appears to be working, but when I get to the "enter 19 digit sim serial code" page it rejects my serial number as incorrect, when it definitely IS correct. Now, my sim is working already, I've just made a test call, but obviously I didn't get to the "Finished" screen on the o2 page. It's still in the full size sim body, should I now pull it off and put it in my new phone regardless?
