Lock codes available for Lumia 920?

I have a locked Nokia Lumia 920. It is locked to Orange/EE UK. Last time I went to Mobile Market Saddar (Karachi) around 6 months ago the shopkeeper said that it cannot be unlocked.

So any new update regarding this?

On forum PakGamers there is a guy who unlock all worldwide cell phone carriers. The service is reliable and the prices are far cheap than market.

Here is the direct link to his section.

Hope it helps in your case!
