So here is my issue, I had an app that allowed me to use my phone as a hot spot it worked fine until the upgrade. I dont have a back up of my old set up didnt know how to and still dont. I need to go back so that I can use my old hotspot app for my tablet. ATT wants to charge $50 to use an application that should be free. They want 50 a month. What can I do to revert to the older version? I can not stand the fact that they actually forced a new firmware on me and did not allow me the choice to choose if I wanted it or not.
