MySpace

For those of you with Myspace, this is great. If you ever accessed the mobile website that Myspace tried to do, this is ten times better. Has automatic login, which is good in my case. Allows for commenting, messaging, posting bulletins, accepting friend requests, and viewing your friends. Profiles are optimized for slow connections and size. You can add photos from your photo library or take pictures with your camera (if you have an iPhone). Also, you can update your status. Free also.
