I have a contract with Vodafone UK but the signal at my hse is choppy, my friends on Orange come on over and they can use their phones practically anywhere in my hse, so I decided to get an additional storm, unlocked it and got myself an Orange sim, rang them up to activate BIS and was ready to pay the �60 annual fee for BIS and the nice man at the other end told me to put my card away as I had a free 6mth trial. Just thought I'd share that for pple with unlocked bb's that wanna go PAYG dont think american carriers are so generous!
