Caught a post this morning by Dwight Silverman outlining how iPhones are impacted by the Carrier IQ mess:
iPhone users who enjoyed a moment of schadenfreud with news that millions of Android, BlackBerry and Nokia phones have spying software installed by handset makers should wipe the smirks off your faces.
References to the same Carrier IQ software have been found in iOS, too.
I quickly located how to turn this off on my iPhone 4. You should too. If you want the full page text of Silverman's article in the Houston Chronicle, you can check it out here.
