Can someone explain to me how I can check if my iPhone is set up for data sharing with my iPad, both on monthly contracts. As I have twice contacted o2 (once by phone and once by chat) to set this up, both times they have said it has been set up, but if I go to "data sharing" on "my o2" then both devices are showing as able to share data, but I can't select a lead device.
Mark.
