DO NOT DO THIS!!! Especially since there is a public API for this:
http://developer.android.com/reference/android/telephony/PhoneStateListener.html We've been through the whole "don't use private APIs" stuff enough times, so I'll just note: 1. This is not "a bit of an advanced topic," this is outright hacking a fragile kludge. 2. Please do not recommend that people do this kind of stuff at least without the relevant caveats that it is not a supported thing to do and they can expect their app to break. 3. Just because you get something to run on the current G1 today does not mean it is the right thing to do.
