iphone 4s icloud activation bypass

If the Apple ID and password have been used to turn on Find My Phone in Settings > iCloud, you must remember the password to use the iPhone. As an alternative, you can login to the iCloud account from a computer or another iOS device with the Find My app, click Find My Phone, and remove the iPhone from the devices list. You will then be able to restore the iPhone and remove the Apple ID.

He will have to remember the AppleID and passcode. There is no workaround

for Activation Lock.

If he is the original owner and can prove it, he should take the iPhone into Apple

to see if they can help.
