So I noticed my 3G speeds since getting my S3 have seemed slower, so I remembered that thread. Installed it and you can see my results in the picture. 1st three test without, last one with. I was pleasantly surprised. I have done several other tests since this screenshot with similar results. YMMV.
Please make sure to Thank Marcusant.
Edit: Pic only had one result after patch. Added link to actual file, it is on the 2nd page of the thread.
