I'm building a web app using jQueryMobile (primarily) - exclusively for the iPhone 4s, and I'm having the following issue:

The icons that are included with jQueryMobile are not displaying properly (not displaying in High Resolution) on an iPhone 4s with retina display. All the custom icons I've used do display properly in high resolution format, but the default icons are not loading in high-res.

I've verified that this is not just my imagination, as I can see that the file that is getting loaded is "icons-18-white.png" rather than "icons-36-white.png".

I'm not using media queries as this is device specific, and doesn't need them.

Is there something I'm missing? Or any suggestions.

Thanks
