Hello everyone! SO! I found what I believe to be one of my 1st iPhones - lol - but my TEN YEAR OLD is getting to that age where everyone has one and all the other kids want one!! Of course she has asked for my iPhone 8+ lolol!!! ANYWAY!!!! its an old phone, but it will do what she needs IF I COULD JUST REMEMBER THE CORRECT OLD 4 DIGIT PASSWORD!!! someone - please tell me how to get this reset on this iPhone 4S and it not mess with my 8+. Because I know it has the same apple ID - thats NOT the issue. The phone is "disabled" now and says to connect to iTunes..which I did and still can not find how to do it on my own! Just want to be able to ONE - get back in the phone and TWO - factory reset it for her. PLEASE - any info would be greatly appreciated!!!!
