Read it on a website Stevy, cant remember which now it was a few months ago, but the pop up mentioned on the post above was in the same story. Guess they didn't go with either option in the end. How are o2 going to charge other network users for this? Would be better if was just for o2 customers in my opinion.
That's one small step for man, one giant leap for mankind.
Don't get your hopes up. Just returned from my local shopping centre where there's an O2 store but try as I might, even standing inside the store, I couldn't find the O2 SSID even though the hotspot locator says it's broadcasting a signal. As there was only one store assistant with a queue of 6 customers I didn't bother to hang around
