Why can't I see my updates on iphone/tablet when I change my html in ftp?

Clearly I'm lost in the sauce.

But I'm learning and I'm running into a problem.

I'm updating an html file and updating it in FileZilla.

When I check on my cell phone (dolphin and chrome mobile browser) it works just fine. When I check on my pc browsers (Chrome, explorer, firefox), again, all my updates are there.

When iphone users check, it looks like it did months ago. Granted, what i looked like before I started working on this website for my friend.

Any clue as to why? Please point me in the right direction.

Surely the new code is not compatible on the IOS

You need to refresh the source of the server as browsers like to do something really annoying called caching, this is where they store parts of a page in order to make them load quicker next time.

Either refresh from source or delete all browser history and anything else that the mobile browser lets you clear.

The answer that it is because the source code is not iOS compatible is RIDICULOUS as any broswer has the capability of reading HTML/CSS even if it is now HTML5 you would still see changes but they may not be displayed correctly.
