Social icon VK.com

1. First you need to create a new options for that. You can do this by adding these lines of code inside options.php file. Add it somewhere along other social icons.

$options[] = array(	'id' => 'social_vk',
					'desc'  => __('Vk.com', 'unite'),
					'std'   => '',
					'class' => 'mini',
					'type'  => 'text');

2. Now that you have created an options you should create an output to make this icons visible. For that you should go to extras.php file and add this line:

$output .= unite_social_item(of_get_option('social_vk'), 'Vk.vom', 'vk');

You can add it right after this line of code:

$output .= unite_social_item(of_get_option('social_vimeo'), 'Vimeo', 'vimeo-square');

Now vk.com icon should be visible.
