Hello all, I've created this account, hoping that someone could assist me with this issue. I'm sorry if this isn't the right section, and if not, please move it to the correct one. Pretty much my scenario is that I have to return an iPhone 6s back over to it's original owner (bought the device online; still had an outstanding balance), but before I do, I want to permanently erase everything, as I did everything from the phone (banking, etc.). So far, I've found some data erasers (Wondershare SafeEraser, iSkysoft Data Eraser), but none of them support 9.1+, just iOS 9. I have two weeks to ship the device, so I'm really hoping someone out there can help me find if there's a way to permanently erase all the data, so that it isn't recoverable by data recovery programs and such. Thank you.
