Securely erasing the iPhone
Posted: September 21, 2013
If you are looking to sell your iPhone, or give it to somone as a gift, you should
probably ensure that your personal data does not remain on the iPhone. Most would think
that a restore via iTunes would take care of this. But it does not! It has been proven
more than once, and by more than one person - one of them a programmer with deep routes in
the iPhone community, and the other a state police detective using a forensics data
retrieval kit built by that same programmer - that your personal data survives a restore.
In the case of the detective, he purchased his iPhone via Apple directly (refurbished).
This process takes just a few minutes.
You can read more about this process at Apple's support forums here:
Launch the Settings application. Then press General, then Reset. Press Erase All Content
Press Erase iPhone. Press Erase iPhone one more time.
You'll see the Apple logo and a status bar for a minute or so. The iPhone will then
display the Hello screen. You're ready to set it up. This process has been greatly
improved in iOS 7!
