Why it was a Fierce 15: Carrier IQ was trying to help operators and handset makers see what was going on between the end user and the device and between the device and the network. Carrier IQ's mobile service intelligence platform, combined with a device client, allowed carriers and OEMs to get real-time data on things like what applications customers were accessing, if they were experiencing network slowdowns or even if they were side-loading content.
