The Interwebs have been abuzz over the last 24 hours about Carrier IQ on Android smart phones, allegedly logging user activity including keystrokes. TUAW can confirm that Carrier IQ appears to be included on iOS 5, but that its purpose is most likely benign.
iOS virtuoso chpwn discovered Carrier IQ support in firmware as recent as iOS 3.x on Apple's devices. TUAW confirmed Carrier IQ references in iOS 5 after reading this post on the MacRumors forum and evaluating the /usr/bin/awd_ic3 file found in the installed OS.
