You don't actually have to go in to the host file and do all of what was explained above, but it does work. Really all you have to do is open TU and uncheck the box that says something like, redirect to cydia or TU on exit. (I'm at work and don't have TU on my work computer to get the exact verbiage ) then you hit apply and then close the application.
What that does is the same as you described above, just easier.
