i disabled my "find my iPhone " and did restore using DFU mode, unfortunately i don't have skip this step option when it's asking for iCloud verification, so now it's on the iCloud verification screen and not going past that, anyway of bypassing it ?
as i said Europa, she wasn't logged in , as her emails was removed and mine was in place, i don't know what happened, but even Apple rep said it was weird but nothing can be done " on their side " he even had me go into my iCloud.com and delete the phone from my iCloud then said he can't do anything , weird people.
How did you end up at the "Activate iPhone" screen? Did you do a restore? If your Uncle passed away and left that phone, it should have been set up already with his Apple ID, which would have made the phone usable if it were not passcode locked. If you tried to restore it, then you have made it impossible to use without your Uncle's Apple ID. If you know his email address used and his security questions, you could reset the password by following these directions. http://support.apple.com/kb/HT5787
If you don't know the required information, there's nothing you can do, other than selling the phone for parts.
