Help with internet sharing

[featips]

Recently I got an exchange touch pro from Sprint, which uses the official Sprint ROM. I was surprised to find that the battery life under Sprint ROM is much much longer than that under custom ROM.

Now, I decide to give up playing with any ROM, just stay with Sprint ROM. However, I still need the function of internet sharing, i.e., connect my laptop to internet through my touch pro using USB cable.

Anyone can tell me a link for the application implementing this internet sharing? Also, if you can also give link to wifi router, that would be great.

Thanks a lot.
