I gotten a iPhone from a friend that he found, but it was iCloud locked.
At the time there were no iCloud bypase exploits
Today there are:
Checkra1n iCloud Bypass Package
Apple Tech 752 Bypass Tool V3

Free IMEI iCloud checker (An alternative to Apples long gone activation lock status tool)
CopyTrans Manager (For free music without iTunes)
But that is not the reason I write this.
Because iCloud lock is been removed already :-S
Today i turn on the iPhone and it seems its been removed.
My guess is that the previeus owner removed the iPhone from his iCloud account.
And the only reason why he would do it is because of Apple will only allow 5 device / account.
So if you own all 5 devices. iPhone, Macbook/pro air , Apple Watch, iPad and iMac.
Total Apple Fan boy! = no protection!
Your screwed if you lose one of your device and replace it with a new one,
you lose the lock and the finder can use your iPhone.
Since Checkra1n is the new jailbreak to go I did that and installed and rsyncd the hole iPhone
to my computer.
Just to look, the first time I wiped the data. But its cool to see the whole layout of the iphone.
And yes it got Cyndia so BigBoss is already on it 😀
