This is just a general question/observation. Lately I've noticed that when I am in a place (Home,work) were my phone has a known Wi-Fi connection, it seems my phone will automatically turn off my sprint data and turn on my Wi-Fi. I am going in to settings and turning my Wi-Fi off, I know I am not leaving it on, and when I come home it will be on and the mobile data will be set to off. I have the EVO 3D. Has anyone else noticed this happening? I know I heard At&t was looking into doing something like this to help with their data issues is Sprint doing the same?
