Okay.......I picked up an S4, Friday after work and absolutely love it. Foxfi works like a charm, with the major difference from the Bionic being the look of Verizon's hotspot (as shown in the pic Wicked posited). You shouldn't do anything with that hotspot button, as explained before, Foxfi exploits and uses the Verizon hotspot to provide your access. Once it says that Foxfi is up and running on the Foxfi screen, you're good to go. :icon_ lala:
And as soon as I figure out how to remove the Bonic pic from my signature, it'll be gone.
