I did update my Ipad Mini White to new IOS 7, and i did accept for an alphanumeric code, a code of four numbers, and only i do not remember it anymore, but the alphanumeric code did set up automaticely for unlock the Ipad Mini, only that, seen i do not remember it, it will always de-abilitate Ipad Mini, and i will can't use it EVER ANYMORE! Help, someone can say me can i get my alphanumeric security code back trough PC!?
