Has anyone figured out why 4.1 doesn't tether and 4.0.2 does on VZ Access without paying the additional $15 per month? Just kinda odd to me that there is a slight variation where authentication doesn't go through.
Verizon has not yet released v4.1 to their customers. They probably have something specific to them added into 4.0.2 that you wont get when using another carriers version of the OS.
