PSN Friends lets you view your Playstation Network Friends list for FREE. Because its cool to see whos online but not cool to pay for it.
PSN Friends is very straightforward.
(Playstation.com is slow so it can take a while to load your friends, even on WIFI.)
Similar to the other PSN apps you will not be able to send messages, because unfortunately, it is not supported by Playstation.
