When buying or receiving a used iPhone, what security precautions should I take?
I intend to immediately wipe the phone by using iTunes to install a fresh iOS, as a clean install.
➥ What else should I do to address security concerns?
➥ If this phone had been through a jailbreaking, is there a way for me to tell? Is there any risk to using a previous jailbroken iPhone after doing a wipe and install of an all-new iOS?
My Question here is similar to: Steps after buying a used iPhone. But that Question focused on practical issues. My Question here has a focus on security.
The only to-do item I know is to check for the Activation Lock feature being enabled. Apple describes how to do this. Any other to-do items?
