I have seen this requested in the past, so I thought I would pass it along:
How to: Get Wifi Tethering working on the Verizon Omnia I910
**** If you have installed any other ICS files before you will need to do a hard reset. ****
Use the files I have attached.
1. Download/Install the attached "ICSInstall.CAB" file.
(You may not need to do 2 - 6 but this is how I got it to work.)
2. Restart your phone.
3. Test the install by Connecting the USB cable to your computer.
4. Then run "IntShrUI" from the Programs Menu and select "Connect".
5. If done correctly the program should display "Connected".
6. Now select "Disconnect" and disconnect the USB cable.
7. Download/Install the attached "WMWifiRouter91.CAB" file.
8. Restart your phone.
9. Turn on Wifi.
10. Run WMWifiRouter from the Programs Menu.
11. Select "Connect"
12. If done correctly the program should display "Connected to WMWifiRouter Ready".
13. From your computer search for the "WMWifiRouter" wireless connection.
14. Now have fun surfing the web from anywhere.
*You may need to restart your phone and repeat steps 10 - 14 a few times to get it to work.
