bootstrap columns for iphone and ipad are the same, how to get another size


I have been developing a bootstrap website and I have found 1 very major flaw, it treats tablet size the same as phone size, the col-xs-x (for 768px and under)  applies to iphone and ipad alike.

With my design I use 2 columns for desktop and tablet size, once in the phone size I want it to be 1 column but bootstrap has no way to do that

I know I could create 2 copies of the exact same content and use media queries (e.g. display:none, display:block) and swap them out for under 480 pixels, but that seems like it goes against the whole point of using something like bootstrap..

Is there anyway  to use bootstrap's columns to accomplish what I want..

col-sm-3       for  desktop (4 columns)
col-xs-6        for   tablets  (2 columns)
col-???-12  for phone  (1 columns)

You can change / create some bootstrap column size definitions
See examples like

You can modify the current bootstrap configuration to another set of limits for each column type.

<class="col-xs-3 col-sm-6" id="iOS"   >

(could add a second column to your row and style in this fashion as well)
