Esteemed DF'ers

Two months ago I upgraded my bulletproof galaxy S3 to a new shiny galaxy S5.

Over the weekend the main camera stopped working on the S5.. So I took it to the Samsung shop in Bradford (yes, bradford is a shit hole) and they tried a software fix.. but to no avail... so I have had to send my 2 month old phone back to the manufacturer for a HW fix and will not get it back for 7 to 14 days!..

No problem, I have a Galaxy 3 at home and i'll just stick my new sim in there.. Nooo.. As orange changed me from and Orange contact to an EE contract the sim doesn't work in the old phone!! the phone keeps asking me for a sim unlock code! I called EE and they can not help.. an unlock code would take 60.. yes 60 days and cost £20. CUNTS

My S3 is jailbroken and running a custom rom.. I am familiar with ODIN and recovery console..

Is there a quick way that I can unlock this phone to any network. I am lost without a phone.

All help greatly appreciated.
