I sold my old phone at the weekend. I was honest in my description and put that it was locked to orange.
The day I posted it the buyer left me feedback saying he had received it
I got an email off him yesterday saying that he had tried using it and it said 'phone restricted' I know it did not say that the morning I sent it.
He has sent me an email this mornnig saying he has tried a few sim cards and it is saying the same so he has returned the phone to me, giving me a RM tracking number.
I know for a fact that it worked, it sounds like he has tried to unlock it and it hasnt worked. I also did a search on his name and he has bought a few of these phones within a few days of each other.
