Nilay Patel, writing for The Verge:
The Carrier IQ smartphone tracking scandal continues to grow, but we’ve just learned some interesting news from an extremely reliable source: the Google Nexus One, Nexus S, Galaxy Nexus, and the original Xoom tablet do not contain Carrier IQ software. Each of those devices was launched in direct partnership with Google as the flagship for a new version of Android, so it seems that the addition of Carrier IQ comes from OEMs and carriers after Google open-sources Android’s code.
Assuming that The Verge’s source is from Google — which could well be a wrong assumption, but that’s what it sounds like to me — it looks like Google is moving to distance itself and Android from Carrier IQ. If this turns into a scandal it’s going to get pinned — correctly, it seems at this point — on the carriers.
