Disable Phone Altogether
So like some of you I've long since stopped using my Xperia Play as a cel phone, for various reasons, but I still like the little guy and want to use it as a portable gaming device from time to time and I have a relatively simple question that I'm unsure about
Is there a good method (besides airplane mode) to just completely disable the phone capability of the device? Like a build.prop tweak of some kind?
Ideally I'm looking for something that will also disable the "no sim" notification in the status bar and just shut off the phone radio entirely.
