Looks like it's having trouble again. I got my order in but trying to back through the system gives an error when you hit "continue" after the accessories section.
After trying the online store repeatedly, I finally picked up the phone and called their telesales team. Had to hang up and call back probably 5 times until I reached a real person.
Once I had done that, everything went smoothly.
I'm now awaiting my 32GB black wi-fi iPad

Got through! Couldn't pick the right smart cover because all those images were broken - but I didn't want to screw around and risk losing pre-order.. will be able to grab smart cover in store 5 mins from my house. Unless there's some mad rush for those.................
