If you databind the IsChecked property of a ToggleButton to a bool? property in a ViewModel and then change the value of the ViewModel property from true to false while the page that contains the ToggleButton is memory resident but not the current displaying page, the ToggleButton does not update its IsChecked property to false.
When you navigate back to the page containing the toggleSwitch, it shows as On when it should be Off.

Also started using MVVM for my Phone apps and looking forward to see a fix for this.
Btw, andywigley, cool blog article!
