XDA member motcher41 is a HUGE Netflix streamer and was sick of the buffering and waiting to watch something, or continue watching something. So he went in and did some digging. Root is not required to solve this problem, but can be a bit easier since you would be able to avoid an unnecessary call to Sprint.  The whole process is pretty simple and painless, and just requires some careful navigation and a simple port change. Motcher41, along with other who have left comments on the thread, seem to have been experiencing a much better streaming experience. He even states that after the switch he had zero buffering over a 3G connection. Never hurts to give it a try.
Direct you self over to Motcher41’s XDA Thread for full and detailed instructions. As always, if this results in damages to your phone, your cat being eaten or patient zero for the zombie Apocalypse you were warned.
