I am running ViperROM and it has the Hotspot unlocked for use. I cannot find anywhere that it talks about the hot spot working only with 3g and not 4g. I have searched google and this forum. I turn on hotspot and it disables 4g and switches to 3g. I try turning 4g on while hotspot is on and it wont start up 4g. Is this normal for ViperROM? Or is this normal for the Sprint Hotspot service? Their Sprint advertising make it sound like you get to use 4g when you use the hotspot Solution: Use Wifi Tether app from the app drawer. It comes with ViperROM and allows the passing 4G data via Wifi from the phone to your other device. App has nice features as well.
