IBM developerWorks now offers a url optimized for the Apple iPhone.  
If you go to the url on your iPhone (http://www.ibm.com/developerWorks/iPhone) you will see a list of the top stories representing each of the zones, brands and topics on developerWorks. 

Text in quotes is the audio for this video. 

"So, say you want to read the top stories from IBM developerWorks...
And you have all these developer topics to select from."

On screen, you are shown a list of developerWorks topics, this list matches the developerWorks left website navigation.
Some options are Open Source, Java, WebSphere, and so on...  (the video scrolls down the page to show all the topics)

"Ok, say you choose Open Source" 

Choosing Open Source or any other topic will bring up a list of Open Source article titles

"You can read the blurb for that article... or you can visit the developerWorks site on your iPhone."

You can click on an article title to read a blurb of the article or can directly select the link for the article - you will then be taken to the developerWorks website through the Safari browser on your iPhone.
