Yup, but they're gonna be chasing that curve again soon unless something in the industry changes
"Is voice over LTE a conundrum?"
Both LTE and Wimax services will need circuit switching to handle 1x voice, until VoiP take off, which could be years. At least SVDO offers Sprint a chance to upgrade their 1x network (which they will need for a long time, same with Verizon).
