I did the port 8080. same results , wifi loads with live video stream and 4G stuck at loading?  
  
I loaded "Log me in" and it works great with live stream , there is a  slight lag tho but good! And there is a bit more button pressing to get there. 
  
Anybody got t-mobile working? maybe its the new app, don't like the GalaxyS2. 
  
thanks
