"IF you have an iPod/iPhone, please make sure that you are not on the mobile version of Pinterest.com when you are on Safari. How do you know? Open Safari, go to Pinterest's website, look at the URL bar and make sure that the URL says: http://pinterest.com and NOT http://m.pinterest.com. See the 'm'? IF your Pinterest website shows this mobile version, you need to select 'Full Site' first before you can make the below tutorial work.
Here's an example. I was on the Pinterest website using my iPod. You see the 'm'? Yes, NO NO!! Look to the right, next my avatar is a drop down arrow. Click that! You will see three option with one being 'Full Site'. Click that and you now should have the regular Pinterest website - it'll look the same way as when you look at it from a regular computer screen."
