If you edit your ItemTemplate to use a ContentControl instead of a TextBlock, the selected item will use the phones accent brush (make sure you aren't setting the foreground color for the content control):
<toolkit:LongListSelector.ItemTemplate>
<DataTemplate>
<StackPanel Margin="20,0">
<ContentControl Text="{Binding n}" Style="{StaticResource PhoneTextExtraLargeStyle}"
FontFamily="{StaticResource PhoneFontFamilySemiBold}"
Margin="12,5"/>
</StackPanel>
</DataTemplate>
</toolkit:LongListSelector.ItemTemplate>
To be able to set it to a custom color, I ended up overriding the constructor for TemplatedListBoxItem and set the DefaultStyleKey: DefaultStyleKey = typeof(TemplatedListBoxItem); I then set up a style for TemplatedListBoxItem that matches the ListBoxItem style in System.Windows.xaml except for a different selected item visual state color.
