I use Openzone every day it is a fantastic bundled service. Anyone is more than welcome to use my hub's hotspot.
Don't have a fancy iphone but I log in with my aging BT2Go phone or laptop with my primary email address and password and never had a problem.
Most of the hotspots have a 'click here' if you are bt broadband customer on the landing page somewhere.
Initially I was only opted in and broadcasting an Openzone hotspot from my hub and I manually added Fon later so I am not sure if you have to have both, but if you use one you might as well use both.
