This is given in the Speaker's response. The costs have been minimal. We currently have the infrastructure to support the iPhone, so we didn't have to invest in new infrastructure to support iPhones. What we had to do was expand our existing infrastructure to buy specific licences for the pilot, so the costs were really minimal. That will be reassessed if we decide to move ahead with the introduction of the use of iPhones, but it hasn't been decided yet. We're waiting until the end of the pilot to seek feedback from members.
