I have a Nexus S (I9020A model). I bought it with an AT&T contract. Isn't the portable WiFi Hotspot feature supposed to be free on the Nexus S? I can turn on the hotspot, and I can connect to it with my iPad. However, when I try to browse the internet on the hotspot, it says that there's no internet connection. Help! 
My software version is 2.3.6. The build is GRK39F.
