I've been having issues lately. I've rec'd text messages from t-mobile telling me that tethering has been blocked and to buy a tethering plan. Additionally, when using pc-suite mode with windows or ubuntu, i get blocked and redirected to a web page telling me to buy a tethering plan. Pc-suite mode dials in a seperate connection and your computer gets a different IP address than your phone.



However this is not an issue when using mobilehotspot, as it uses NAT. Worked fine for me in USB mode on ubuntu, and with wlan on windows.
