I sat for hours and could not get it to work. Followed the instructions 100%, tried restarting the phone even at one point and no luck. Tried using the IP that the app gives, tried using my router's IP, tried using my phone's IP...no matter what I do, when I test the connection, the PS3 fails on connecting to the internet every single time.
The app uses some default IP that doesn't match any IP on my network and keeps defaulting back to that one even when I enter different IPs.
