Kill some commented out code; it's no longer needed
Remove the userMapRegion property and replace it with mapRegionWasSet. Since each of the 'setRegion' calls are now run through the map operation queue, things should 'just work' now.
Don't create a map view just for the hell of it; make sure we're actually going to need it and be sure to dispose of it when we're done
Add a method for creating a default content view that fills the entire screen, minus the space taken up by a navigation bar or a toolbar

Fix a bug with ArcGIS happily ignoring little things, like its view's frame.
Don't call [super loadView]! The documentation explicitly says to not do this.

Bit of really minor cleanup. Should ensure that we respect the bounds origin (well, in this spot, anyway)
