Tl;dr how I can unlock old iPhone that I found in the drawer if it's blacklisted?
Hey, recently found an iPhone 4 on local market in eu few years ago. Back then it says that sim is not supported and I don't understand why, now I remebered that I still have it in drawer, charged it, and trough some services I checked this iPhone, and that service says that it locked on EE (formerly T-Mobile UK), so I looked up, and found that they can unlock it for free, I entered IMEI, and I have greeted with sign,that this iPhone is blacklisted, so, now I don't know what to do.
Thanks.
