I've placed and N900 preorder in the Nokia Spain Shop on September 3rd. They called on September 11th and told that the system, by error, cancelled all N900 preorders and they were doing them again.
Today my Nokia Spain Shop account's password didn't work and I had to reset it. I've received the new password by email and now in my account I have two (2) preorders.
I hope they charge me just one (I don't mind if they send me two )
