The docs certainly claim that it was first available in 4.0, but I remember the new MapKit overhaul being part of the diff for 3.2. I think the docs just have the timeline of that update wrong.

Why are MKPolyline and MKPolygon working in iOS 3.2.2 (on an iPad)?
This weekend I was watching Terminator 2 (editor cut). In the end, after T-1000 is destroyed, Arnold asks Sarah and John to destroy him by melting and says "I cannot destroy myself".

So, what does this mean? The terminator cannot destroy himself unless it is absolutely necessary in order to succeed in his mission (like protect John?)?

In that case, what was the Terminator in part 1 going to do after the success of his mission (i.e. destroy Sarah)? Just live a long happy life and wait for Skynet arise?

Update:
I understand that this is not the exact Third law of Asimov, since the terminators definitely don't follow the First or Second law. Let's call it the law of self-preservation. Does terminator have a form of self-preservation to some point and the prohibition of suicide?
