Now that the second-quarter earnings season is over, what conclusions can we draw about how wireless carriers performed? Thanks to a partnership between Jackdaw Research analyst Jan Dawson and FierceWireless, we're publishing slides Dawson produced on the quarter exclusively for a short time. These slides are part of a larger report Dawson has assembled on the second quarter. Dawson's research covers relatively standard metrics including revenue growth and net adds, but also includes deep dives into prepaid versus postpaid performance, subscriber acquisitions versus losses, and more. One of the key stories Dawson saw in the second quarter was Sprint's (NYSE: S) improved churn and customer metrics as well as the continued shift to equipment installment plans.
