It appears the new PayPal checkout is slowly being rolled out to an increasing number of buyers at random until eventually all checkouts on PayPal's site, including those coming through E-junkie, will use their new checkout interface. You shouldn't need to do anything to take advantage of this, as the nature of our service means we manage the back-end software for you. BTW, you can already provide a custom logo/header for your E-junkie checkouts now, by going to Seller Admin > Edit Profile > Upload Your Logo. :^)
