Firstly, you will need this, its free and runs on windows 7:
http://www.bluestacks.com/
Its an android emu, and runs most all android-capable apps.
Secondly, sign up for a google account if you don't have one.
Once you have bluestacks running, go to the app store and search for "planetside 2"
The mobile app will show up as being published by Sony Online Entertainment (duh). Click it, click install. You'll be prompted for a google login, do it.
Once installed, you will receive an error saying it cannot find a smart card or usb drive. thats fine, ignore it and close the error. click the back button until you get to your front page. click on "my apps" and scroll down to the ps2 mobile app. Start it.
Voila. Done.
