Tmobile Wifi Tether Speed Throttle fix

Switched from Samsung to HTC. I've used unlimited, unrestricted speed with Samsung, but I've wanted HTC. Everything's great except my main source of Internet was now throttled. Here's the fix I foundfound.

Create new apn with exact same values as the default, but add "dun" at the end

default,supl,fota,hipri,dun

This lifted the speed throttling = :)
