Quote from burrito_minerI found the PS app on my phone pretty cool, messages come through instantly and you can even send attachments (could be useful screenshotting in game and sending it to someone even when they're not online as it'll go to their phone).
I see some of the other threads being wayyy too serious for my liking. I love an RPG or even MMO from time to time, but I like our chilled approach to MC personally.
I use the psn app with my buddy, and it works great for sending screens around. I get everything while I'm at work.
