Standards are great...

My team has been involved in creating web pages and applications following W3C standards since a long time. These pages render almost the same in all standards compliant browsers save for a few which require additional hacks. Amazingly, when I tried to access the same pages from the mobile phone browser (the built-in xHTML browser as well as Opera Mini), the pages rendered well, albeit in a degraded manner. So my information was all intact and only thing I lost was the columnar layout and some design elements.

(Opera 9.1 Desktop Browser)

(Opera Mini 3.0 Mobile Browser)

Bottom-line: Make your pages standards-compliant and they will be device friendly automatically. You do not need to put in additional effort to make these pages accessible across devices.
