I got on a mobile last night with Virgin Mobile as the provider. They're pretty big with the younger crowd. On their main page (virgin XL), you scroll down to Featured and get:
Yahoo
Facebook
Yolo.mobi

Don't know if this has been brought up, but I thought it was pretty cool.

Off subject, it was cool to see my sites on a mobile first hand. I couldn't play around long, but it was fun while it lasted. I've got to step out of the stone age and upgrade....
