Old Apple ID on iPhone 6
Good day hope you are all well..
I recently received an iphone 6 as a gift from my uncle .. I then went and did a update and restore on my itunes app on pc but when the iphone restarted it now asked me for the old apple id now I know the ID the icloud email but my uncle used the phone so long time ago he cant remember the cell number that was used to create the id or the password , when i try to reset the password i get stuck at the last number associated with the account ...any advice or help will be appreciated
Thanx in advance
