Does any one from India facing usb/wifi tethering issue after ICS update?? have u got any solution for it??
i also face this problem.we need help.
I strongly suggest you contact your operator and request a alternative APN address (and settings) as this is not restricted to one operator/country or device.
Thanks Jeff for your valuable suggestion. It actually worked. I contacted my service provider and they fixed my tethering issue. Once again thanks a lot!!!! 
Contact your service provider for alterations in the settings. I did the same and tethering is now working smoothly. Hope it works for u also!!!
