Only because u see the word APP does not mean Iphone. APPS are everywhere the browser that your usingt to post this is a APP the notepadd u use to right stuff is a APP etc.. APPS are everywhere and there not new things, not only iphone has it.
the idea is great but ps3 is not open source so people cant creat apps like they do on pc iphone androids etc..
i think that would be great. like an app that would let you text a message from your smartphone when you get one on psn... so much faster i think
