"Update: chpwn notes that initial research indicated that Carrier IQ's software may only be active when the iPhone is in diagnostic mode. In a blog post, chpwn confirms that, based on his initial testing, Apple has added some form of Carrier IQ software to all versions of iOS, including iOS 5. However, the good news is that it does not appear to actually send any information so long as a setting called DiagnosticsAllowed is set to off, which is the default. Finally, the local logs on iOS seem to store much less information than what has been seen on Android, limited to some call activity and location (if enabled), but not any text from the web browser, SMS, or anywhere else. We'll let you know when more details arise."
