has anyone or is anyone on at&t here in the states with their ativ s and is able to use internet sharing? I am in a pickle because there is no official Sirius xm app, 3rd party apps no longer work and I use to tether my stiletto to my titan but I don't have that phone anymore. I tried to turn on internet sharing and I get the reject that there is no cellular data connection to share which is bologna because I do have connection
