My Exhibit 4G Model 759 is currently on 2.3.3 and to use the app for my bank I need at least 2.2.8 or higher. I contacted T-Mobile and they do not have updates for this phone anymore. Does anyone know if updates can still be done for this phone and where I might be able to find them? I know next to nothing about this sort of thing so will need help with doing this. Thank you
