Re: Factory Reset
I believe the Blackberry and perhaps iOS phones do the best job of scrubbing the memory,(Don't Blackberry have some sort of security certificate from various government organisations?) not so sure about Android and Windows phones, if you are really worried about the data on the phone, probably best not to sell it on, or manually reset and setup several times taking plenty of pictures or video to write over the older data.
