Sprint Overdrive 4G has still a performance issue on iPhone 4. (w/ workaround)

I have excited about Sprint Overdrive from yesterday. Because I can find 4G signal in some part of San Francisco (which includes my office) recently. The 4G performance seems not good so far. It's around DL/500kbps and UP/1Mpbs via iPhone 4. I was thinking 4G was still non official then the performance was still restricting by Sprint. Actually Sprint's Samsung Galaxy S device had also similar number of result.
But today, Steph (who is my co-worker is sitting next to my booth) has noticed significant improvement of the speed on his Galaxy. He can get DL/7Mbps and UP/1.2Mbps from speedtest.
Then I also have tried testing speed on my iPhone 4 again. But my test result was stillSamsung Epic 4G | Android Central nothing change. So, I'm being to wonder whether Overdrive has something problem.
I could easily found some reports which were mentioning about the performance issue on Overdrive with iPhone.

WTF! It seems Overdrive not get along with iPhone. Even Sprint is promoting Overdrive for iPhone users for getting more speed. :-(
Some online informations told me that there was the firmware update 1.0.7 which fixed the performance issue on iPhone. I already had the latest firmware 2.06.06 but I can't get the performance yet. I have tried some setting changes but nothing was happen.
When I almost gave up, I just reverted the firmware to 1.07 from latest one. I could get a definite improvement DL/2.5Mpbs (Upload speed seems a slightly decrease UP/0.8Mpbs). But it's still slower than 7Mbps which is measured at same place by Galaxy S.
I'm still really jealous of Galaxy S. Overdrive has still an issue for iPhone. I'm seriously hoping Sprint will fix this issue in near future.
Additionally, on iPad, There is no obvious differences between firmware 1.07 and 2.06.06 The performance test is outputting the result as DL/4Mbps and UP/1Mpbs. It's also not equal at Galaxy S but It's acceptable so far.
One more thing, if you using 4G tethering via Galaxy S, iPhone 4 network performance seems still bad less than 1Mbps at my case. It means there is no good 4G capability solution for iPhone so far. :-(
