I have 2 ipads and want to give one to my grandaughter. Do I just hit Reset and then Erase All Content and Settings? The ones I have are an Ipad 2 and Ipad 4. I initially setup the Ipad 4 from the Ipad 2 at installation so I want to make sure if I delete everything from the Ipad 2 (the one I want to give her, it doesnt mess up the Ipad 4. Also, does this method take the Ipad 2 back to original factory settings? Thank you.
