Q:

add carrier name in dropdown same as Fedex and etc

Want to add the carrier name in dropdown same as default carriers in shipment admin panel, how can I set it ?
Please see picture

A:

each carrier must have a model associated to it that implements the interface Mage_Shipping_Model_Carrier_Interface. This interface has 2 methods.  
interface Mage_Shipping_Model_Carrier_Interface
{

/**
 * Check if carrier has shipping tracking option available
 *
 * @return boolean
 */
public function isTrackingAvailable();

/**
 * Get allowed shipping methods
 *
 * @return array
 */
public function getAllowedMethods();

}

You have to implement the method isTrackingAvailable and make it return true. IN the dropdown you see in the backend only the carriers that have tracking available are listed.
