FWIW, Verizon does extensive internal testing of OS updates. When I was there, as an engineer, we would be given phones, and anytime there was a new update, we would receive the updates first, use it daily for a couple of weeks, and report what we found. There were multiple tiers of internal user trials before the updates were greenlit, and there were many potential OS updates that never made it to public because of the problems we found.<p>Verizon may slow down updates to consumer devices, but I always felt like it was for good reason.
