If you concern is basic privacy before selling it, the delete is fully adequate. If your concern is a forensic team extracting your data, then yeah, destroy it.... Then reconsider your life decisions lol.I'm afraid you have to physically destroy the device in order to be absolutely sure that your data can't be recovered afterwards.
Erasing all content and settings is sufficient. The information on your phone is encrypted, erasing all content and settings removes the encryption keys such that the information is useless without these keys.Hello guys. So, I have a iPhone 4s that i'm going to sell and I'd like to erase all data off my iphone permanently. What can I do to make sure no data can be retrieved afterwards?
That sounds pretty awesome. Now I know how to treat old phones from now on.Without a doubt. Will destroy not erase. Kinda like a nuclear magnetic pulse on a smaller scale but just as effective. Be warned as the phone will catch fire, likely the battery, if "cooked" long enough.
