Hi! I bought iphone 6 factory unlocked,it was few weeks old,i was able to put my sim and activate it without any problems,i can also sign in into my icloud account and apple id and password,BUT when i go to icloud.com and enter my imei or serial it is showing activation ON,so my question is OK i can use it and i have full vontrol over device but whats gonna happen if i want to reset or restore device??? Why activation lock is on and i didnt have problems with activating very strange,there is a note before puting serial to check activation that maybe is device need to be removed from previous owner account,what scare me the most is,if one day i need to reset the phone maybe message will pop up and ask to to sign in into icloud account not apple id account which is from the previous owner
