Google Tutor has posted a fantastic post on how to instantly make a mobile phone version of any feed using Google Reader.
All you need to do is add a feed URL to the end of this line :
http://www.google.com/reader/m/view/feed/[feed_address]
So for instance Our blog’s mobile feed would be :
http://www.google.com/reader/m/view/feed/http://webconsuls.com/blog/atom.xml
You could add, Click Here For Mobile Version of Our blog, and link it to the url you create.
Your Blog is Mobile!
