How to turn off Carrier IQ on your iPhone

It is these types of stories that make me wince whenever I am linked to computerworld.com. No new information was offered, the title was primed for linkbaiting, and the rest of the story was a regurgitation of pieces found elsewhere (with extraneous bolding). I wish I could un-see the pre-roll advertisement--not because I hate advertising, but because I can't believe computerworld gets money for that type of story.

I don't know why exactly I followed these instructions, because I was sure that I had never turned "diagnostics" it on. When I saw the settings I was kind of shocked, because my iPhone 4S (5.0.1) really was running in diagnostics mode all the time.

Probably you should check your settings, too!
