Hi folks, I am Kannan from India. I bought a T-mobile HTC sensation 4G thro' ebay and unlocked it. It had gb installed in it. On 15th June, I upgraded it to ICS 4.0.3 but then USB tethering is not working fine. I couldn't connect to the internet through mobile network. I know that T-mobile users gotta pay 15$ per month to use USB tethering but being in India i am using airtel(mobile network) and not T-mobile network. Is it possible to use USB tethering in my mobile? Thanks.
