The instructions for my legend say that I can tether the phone to use internet on laptop. However when I connect the usb cable the only options I have are charge only, HTC synch and disk drive. How do I enable the phone to act as a modem? The phone is connected to a mobile network and browsing with the phone works a treat. Also I have installed HTC synch on the laptop and connects perfectly. I would appreciate any response as this facility would be very useful for my work.
