Hello Everyone, I recently purchased a new IPad so I need to unload my older IPad 2. I am going to wipe the IPad/restore to factory settings before I get rid of it. My main question is does this downgrade the IOS as well? If it does not, should I do tis before I sell it? I just don't want to get a bad rating. The main reason I bought a new Ipad is because this one keeps crashing when using the internet. It has IOS version 9.1.
