I am looking for a few programs.. - A reputable program to completely erase data on an iPhone? I am aware of the factory settings to erase all the content, but I am looking for a program that will also write over any erased files so they are never recoverable? - A program that will clean up the phone (Documents and Data of cahed files not used) - Looking for the same type of reputable programs for my MacBook. I already use CleanMyMac for cleaning, but I need something for permanently erasing files that were already trashed. Thanks!
