Out of all the social networking apps for the iPhone, MySpace does the best job. All of the features from the regular version are available for you to take advantage of with the exception of being able to listen to music on your friends or a bands page.
The app has 5 main areas: Home, Mail, Requests, Friends, and Photos. Your home screen offers you the ability to change your mood and status while keeping up to date with what your friends are doing and posting. Mail and requests simply split the function that your inbox serves on the regular website.
Friends lists out everyone on your friends list, making it easy to message them or post on their wall without having to go into their profile unless you'd like to. And photos will let you browse through your own pictures or add more to your albums directly from your iPhone.
The MySpace app is by far the most complete social networking app available. Unfortunately, MySpace hasn't been the leader on the social networking world for quite some time. While the battle between MySpace and Facebook continues, it's interesting to see that after two revisions, the Facebook app still doesn't offer a majority of the features that the full web experience does. If you still use your MySpace or even have a MySpace, you'll definitely enjoy this app.
