embeded PDF not showing on ipad

Hello,

I have asked people to take a look at my website and the pdf I have embeded is not showing up on a friends ipad (using Safari)

http://designpush.co.uk/curriculum-vitae/

looks fine on IE9 and on the safari on iphone. I have asked them to clear the cache.

Anybody any ideas what the problem could be?
