Interested in selling or giving away your old iPhone, iPod touch, or iPad but need to know how to make sure you've erased all your personal information from the device first? Luckily Apple makes it easy to securely wipe all your data. We'll show you how after the break.
Although we highly suggest performing a full firmware restore and setting up your iPhone, iPod touch, or iPad as "new", if you're not near your computer you can still get the job done:
If you have a passcode setup, you'll have to verify your credentials before being asked one last time that you're positively sure you want to dispose of everything on your iPhone. The process can also take some time depending on how much music, video, apps, etc. you had stored on the iPhone, and Apple is writing over the data multiple times for security's sake.
Once it's done you're good to give away or sell your iPhone, iPod touch, or iPad without having to worry about anyone getting into something you may have left behind. Let us know if you have any questions in the comments below!
