jjwang: I'm not an expert on this by any stretch (seeing as how I just did it) but I followed the directions exactly as they are in the first post. Use a registry editor (I like PHM) and go to HKLM\Comm\InternetSharing and just delete the ONE string that's there (you don't have to bother with renaming it...it doesn't hurt anything by deleting it and you could just type it back in [I only say don't rename it since you're having issues]). Once it's deleted leave your phone alone for a couple minutes and go grab a drink or something. After about 5 minutes come back and soft reset the phone then just continue to follow the directions. I used software to soft reset because I've read on other forums that you can't pull the battery as the reg edits might not take, I've normally never waited 5 minutes or worried about how it soft reset but who knows...I had a spare 5 minutes. Brief summary again
1) Registry Editor...
2) HKLM\Comm\InternetSharing
3) Delete this string: Extension - IcsHelper.dll
4) Wait 5 minutes and grab a Coke
5) Soft-Reset
6) Establish internet connection (open Internet Explorer etc)
7) Plug in USB cable to computer and phone
Start -> Programs -> Internet sharing -> Connect
And that's it. I followed those steps and it worked perfectly. Here's my speedtest (says file's over the limit. blah:
