Oh, a handgun. How nice.
You know, every now and then, someone brings me his iPhone which happens to have an iCloud Lock. It's basically the same as the Google Account Verification Lock. Except, it's currently "impossible" to bypass it, meaning, there's no official/unofficial way or hack or something. Whenever someone comes to me with such an iPhone, I laugh and offer them my deepest condolences for they have a thousand dollar brick.
There are many web services claiming to be able to unlock it or bypass it but 99,9% of them are scam. The remaining 0,1% will charge you a horrendous amount of money but probably will be able to unlock it. Your only hope is to nicely ask Apple and only if you have the official, legitimate receipt with your name and matching IMEI/SN. If you happen to do this via E-Mail/Phone, I'm sure they'll somehow ask you to verificate that it's really the person on the receipt they're talking to. Still, I know of people who even then couldn't get their iPhones unlocked. Also, if I'm not mistaken, they have a challenge going on that anyone who's able to hack or bypass the iPhone, which should include an iCloud Lock bypass, may have a 1,000,000$ prize. A group of people recently claimed this prize. Not because they bypassed the Lock but because they managed to "hack" themselves into iOS 9.x only via Safari. And of course, they only told Apple how they did it. At least, they only provided Apple with the technical details and resources. If these people are "legit" with their cause, why the hell would they publish instead of talking directly to Google? Maybe there's no prize money. Maybe I'm not getting this. Either way, it's shady af to me.
