HELP! Weird Text Appears on iPhone Safari Version of Website

So this is an easy problem to explain, since anyone with an iPhone can see it themselves.

We run an education reform news website, shown here:

• http://ChoiceMedia.TV

It looks correct on all our in-house laptops, both Mac and Windows, in whatever browsers we try.

But on any of the iPhones we try, at least the iPhone4s, there are weird spammy text characters that appear right in the middle of the homepage (if you zoom in to the "today's video" area, you'll see them clearer. They appear on lower-level pages too.

Our site is run on WordPress 3.5.1.

Does anyone have any idea where we go to remove this from our site???

Thanks in advance!

 

The problem isn't connected to a particular page. Meaning the exact same spam text characters appear on not only the home page, but in all the subpages too:

• http://ChoiceMedia.TV
• http://choicemedia.tv/2013/02/14/study-states-lack-principals-data/
• http://choicemedia.tv/2013/02/12/reformers-split-on-tx-school-funding-ruling/
• http://choicemedia.tv/2013/02/06/the-abcs-of-school-choice-2013/
• http://choicemedia.tv/2013/02/04/states-average-d-for-teacher-prep/

So the problem characters have been put not in the posts, but somewhere else in the Wordpress code. Any ideas?
