I've been really overwhelmed due to the several techniques that exist out there and i imagine that nothing can stop a true hacker to regain some data out of any device that keeps data. Especially magnetic mediums. Is that different with the iphone though? I know that it uses flash memory and i am not sure how easily can that be compromised. I know it sounds stupid, but with the advancement of technology, even though it might be not so easy to recover data, even when using the erase data function on iOS but what about in the near future? Some smart stephen hawking of IT might invent a hacking utility that compromises data in seconds.. Could you please give me some insights about me selling my iphone? I don't wanna end up having random people having a look on my personal data. I am thinking as a last resort to disassembly my iphone and sell it as spares not including the flash chip... Thanks!
