Ok everyone…. I think I fixed the text caption sizes on various mobile devices. I tried this on my live demo site http://demo.styledthemes.com/preference/ and I tested it in this http://mattkersley.com/responsive/
I also just tried this on my iphone and looks good, but let me know how it works for you. If all works well for everyone, I will update the “preference” template for the widgetkit slideshow in the download package.
