Unless we are referring to a specific market. I have been using the hotspot settings in Settings->Personal Hotspot on a Verizon iPhone 4 for quite some time.
This morning the Settings->Personal Hotspot was gone. I changed nothing with my plan, nor with my phone.
Note, as of this writing, Apple/Verizon has not released 4.3 for the verizon iPhone 4.
Thanks for any advice as to
why the option might be there one day, and gone the next.
Thanks,
Andrew...
