I'd love to use the Mobile Hotspot on my Verizon phone, but I fear turning it on and getting a bigger phone bill. I have a grandfathered unlimited data plan. Does anyone have experience with this? If I turn on Mobile hotspot will the rate go up? Edit: I found a thread that stated it will only be free if I root the phone. First, I'm not smart enough to do that. Second, I have Android 2.2 with an update, on an Incredible I and I think I can't root anyway. But I'd still like to hear from anyone who has Verizon and is using the Mobile Hotspot feature. TIA.
