Improve restricting IMSI

[Cyclu]

With Elixir2 I can read IMSI MCC+MNC with /system/build.prop restricted (has the usage data) restricting shell/exec has not effect here like for hostname as I said in the another issue. In the build.prop I found this two prop:
gsm.operator.numeric]: [00101] MCC+MNC
gsm.sim.operator.numeric]: [00101] MCC+MNC

With Elixir2: Open Information screen>go into software page with right arrow>tape Configuration>More Information

I do not really understand why you can get the mcc/mnc this way, but I will restrict it:

getConfiguration:
http://developer.android.com/reference/android/content/res/Resources.html#getConfiguration()

onConfigurationChanged:
http://developer.android.com/reference/android/content/ComponentCallbacks.html

Really I don't know why it see the usage data for the build.prop you have the same result with Elixir?

Even if I access directly to this screen in the Elixir2 I has the usage data for build.prop surely it's
a coincidence. Restriction works perfectly we have the fake data!
