Sorry If this has been asked before.
I am thinking of debranding my Orange lumia 800.
Do I need to sim unlock the phone first or at all or once its debranded will my sim work? I ask because after debranding my HTC Desire I had to sim unlock before the phone would work properly.
Also are there any decent guides to follow I found one here that seems ok.
Any thing I should be aware of with the Orange version of the device before I dive in?
Thanks for any help.
