Sprint Sends Out Pre Marketing Postcards

This was posted on Engadget’s comment thread, and it appears to be a marketing postcard that one of the users received in the mail. I, like many others, signed up for the email notification from Sprint regarding the Pre release date, but so far have gotten nothing in my inbox. It seems that some people are receiving these postcards and only points towards the June 7th release date. Get your wallets ready, fanboys!
