                    <DataTemplate>
                        <Border Background="Transparent" Margin="12,8,0,8">
                            <Border Background="{StaticResource HighlightBrush}"    
                                        Padding="8,0,0,0" Width="62" Height="62"

                                <TextBlock Text="{Binding Key}" 
                                        Foreground="#FFFFFF" 
                                        FontSize="48"
                                        FontFamily="{StaticResource PhoneFontFamilySemiLight}"
                                        HorizontalAlignment="Left"
                                        VerticalAlignment="Bottom"/>
                            </Border>
                        </Border>
                    </DataTemplate>
                </toolkit:LongListSelector.GroupHeaderTemplate>
                <toolkit:LongListSelector.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Margin="20,0">
                            <TextBlock Text="{Binding n}" Style="{StaticResource PhoneTextExtraLargeStyle}" 
                                       FontFamily="{StaticResource PhoneFontFamilySemiBold}" 
                                       Margin="12,5"/>
                        </StackPanel>
                    </DataTemplate>
                </toolkit:LongListSelector.ItemTemplate>
            </toolkit:LongListSelector>

the LongListSelector without a "ItemContainerStyle", i don't know how to set a Style Resources, like normal listboxitem.

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.
