I did something very stupid and need help. My friend gave me an old iphone 1 from the US where the sim card is integrated. I was deblocked for usage in France where I live. I was using it fine with my French sim card and decided that I wanted an application that my current software didn't support. So I updated the software and OF COURSE, since it had been deblocked, it has now reblocked and I cannot use my SIM card in it. I can't even turn it on because I don't have the old sim card. Is there something I can do?
I backed up the old phone settings but since I can't even get past the lock screen, this could be a problem.
