What are your favorite mobile web sites? Not just sites that play well with mobile devices, but sites specifically designed for use with a mobile phone.

For me:

1. http://m.facebook.com/
Features mobile-friendly access to your status field, messages you've received, and a mini-feed of your friends' status fields and more. You can also upload mobile pictures and video from your BJ2, which is pretty slick.

2. http://m.youtube.com/
Converts their FLV video streams into something that the BJ2's Media Player will support -- and it works VERY well.

3. http://m.myspace.com/
Features mobile-friendly access to your profile, mail, blog, friends, lets you search for other users, and alter your settings.

4. http://m.cnn.com/
CNN News

Mobile sites that I wish worked:

1. http://m.linkedin.com/session/new
Gives me a login prompt but won't accept my login credentials.

So what are your favorite mobile sites?
