Hi! I have a question - is there any rule when Apple Online Store checks validity of my identify and credit card (sending email with request to send them any document that confirms, that everything is legit), or they are doing that randomly of maybe only for the first order? Because latestly I ordered iPhone 4 and get that email, so I decided to cancel my order because I don't want to send them my personal details via email, so that's why am I asking, if it's possible or are there any chances to slip through, and omit this "security check".
