Change ISO Code to Country Name on Zone Rate Shipping

Does anybody know how I would go about changing the ISO CODE to the actual Country Name when using Zone based shipping.

E.g. Change

Shipping to EN

to

Shipping to ENGLAND

Edit the shipping module zones.php and add the code in RED:

  function quote($method = '') {
    global $order, $shipping_weight, $shipping_num_boxes, $total_count;
    $dest_country = $order->delivery['country']['iso_code_2'];
[B]    $dest_country_name = $order->delivery['country']['title'];
[/B]    $dest_zone = 0;

around 309:

              $shipping_method = MODULE_SHIPPING_ZONES_TEXT_WAY . ' ' . $dest_country[B]_name[/B] . $show_box_weight;

around 340:

              $shipping_method = MODULE_SHIPPING_ZONES_TEXT_WAY . ' ' . $dest_country_[B]name[/B];

around 374:

              $shipping_method = MODULE_SHIPPING_ZONES_TEXT_WAY . ' ' . $dest_country[B]_name[/B];
