Carrier IQ: Which wireless carrier is the biggest user?

The Washington Post writes Carrier IQ: Which wireless carrier is the biggest user? "In response to a request for more information from Senator Al Franken, AT&T, Sprint, Samsung, HTC, and Carrier IQ have responded with letters detailing their use of Carrier IQ's software on their handsets. Sprint is by far the biggest user of the software, admitting to installations on 26 million devices. Additionally, HTC has, for the first time, directly and publicly addressed the fact that Carrier IQ blames it for the insecure log files found on its devices — though not in a way that's likely to satisfy unhappy users. Another surprise: AT&T's network and dropped calls reporting app, Mark the Spot, utilizes Carrier IQ (though not on the iPhone).

All told, it's safe to estimate that Carrier IQ's software is installed on over 30 million US devices and now, for the first time, the companies involved are publicly naming them. We break it all down for you below."
