A friend of mine has just accidently updated her iphone 4 to stock firmware. She was using a Gevey sim and using an O2 simcard on an orange locked iphone. Anyway now she is on a new baseband and 5.0.1 and the phone obviously is no longer seeing her sim. I have tried to downgrade it to 4.3 as tinyumbrella is reporting blobs for that firmware but the downgrade is failing right at the end. Is there any other way to unlock the baseband? She rang up Orange and they refused to unlock it as she was not the original owner. She has no way of getting hold of the old owner as it was originally purchased through ebay and she no longer has his details.
