ladies and germs, I literally spent all day checking this out. I ran into dozens of spam websites and a ton of articles that dated back to 2009-2011 and focused on the older iphones. I am selling two iphone 4S'. I restored them via itunes twice and changed my apple id. Is this sufficient for wiping out all the data? What I have read is that apple encrypts all data on the iphone and merely wipes out the encryption key to "delete" all the goodies. How secure is this? While I dont have state secrets I do have two years of my life on these bad boys. I mean is there any one out there open source that has broken the apple encryption? These smart guys with CS degrees break this stuff all the time, but I do have faith in Apple. Whats the LATEST word on this? Once again I am talking about selling an iphone, where the new user would have no access to the previous backups on my computer. What can they access with just a restored Iphone. Thanks for you help!
