just did it a bit ago using qpst, my speeds are better but the difference is not that much.
Here are my results in Miami, FL by Kendale Lakes.
The bottom two are before changing anything
The two in the middle are the speeds from my wifi, did it just to compare.
The top two are after changing to Simple IP only.
Better than nothing I guess. I can confirm it works on our phones, Im rooted on Reppards CM7.1 Rom, PRL 3026.
And Im on Windows x64, did nothing special everything works with the instructions given on the thread.
