So 56006 is the fastest so far? I manually loaded it, and doesnt seem to be any faster,and actually seems to connect to LTE less. Whenever I dial *2, it gives me the "Welcome to sprint" message, versus the "welcome to verizon" message I got when I had 52644 loaded on my 4S. So is it safe to say that this is a sprint prl, and not a verizon 3G/ sprint LTE hybrid prl? Because THAT would be sweet lol
