anyone know about this, i have seen huge posters up all over and got a text message saying you have 500mins a weekend for 2months and it has loaded, and i was still getting charged for them, i went in the o2 shop and they rang the head office and said you only get them free if you here a wisper saying you are in the zone, that means you have to keep ringing the number to get on one thats free, ie annoying who ever you are ringing, i think this is a load of c**p.
