Q:

How do I fix a sticky scroll on a mobile responsive website?

I am building a mobile responsive website. 
I noticed that when scrolling the page using an iPhone, the scroll is sticky and not smooth, while on android mobiles it's ok. 
What can be the cause of this sticky scroll? I cant even see it on my browser!  Please take a look at my code on JSfiddle. The images won't load but you don't need them anyway (you can see their borders). I recommend you to use 320px width to view the page so the icons are all organized. 

A:

So there is this line you can add to your body or the main div: -webkit-overflow-scrolling: touch; 
Made the trick.
