The Google Reader Blog announced that you can now use Google’s RSS reader, Google Reader, on your mobile device. To access your RSS subscriptions at Google Reader on your phone or mobile device, go to http://www.google.com/reader/m.
I gave it a try on my Treo 650, and besides for it messing up when I logged in (taking me to a not found page), it worked fine. It is quick and easy to use. This is a nice addition to Google Reader. I am personally a heavy Bloglines user and I use Bloglines on my mobile device probably daily.
