I noticed one day after my speeds had been throttled that they suddenly shot back up, so I did some digging and came across a post that had a simple easy and fast solution...
When you have 4g signal place your hand over the top of the phone until it switches to 3g
Then remove your hand and sit the phone down. If your 4g signal is strong enough it will soon switch back to 4g and your throttle should be gone.
*This is not a permanent fix, you will have to do this each time you notice your speeds are throttled
I use PDAnet to tether my internet to my pc and have used this method to download movies, games, shows, music etc, well after I was throttled.
speeds changed from 24/kbs to over 2mbs
*Also my phone is not rooted
