MySpace was the original social network, and although it has recently seen a significant decline in users and popularity, it’s still relevant. I’m impressed with how much you can do with their iPhone app. If fact, it incorporates almost all of the Web app’s main features into a simple and easy-to-use interface. You can even upload pictures or video that you take on your iPhone straight to your MySpace page. MySpace Mobile is a great mobile alternative for the desktop experience.
