I have the GM installed and it works for me but crashes pretty quickly. I am using Windows 7 and Safari 5 to connect if it matters. I travel for work and need to tether bad once in a while. I never use much bandwith when I do it as its usually to use some work tools. I currently pull the SIM out and put it in my Windows Mobile phone to tether but am so sick of that and I have owned Netshare from way back. I suppose at some point I should just consider jailbreaking but I do hear mywi doesnt work with iOS4 and pdanet isnt that great but I never tried this.
