Read about people doing this all the time etc, I'm on an 18 month with Orange, due to run out in August, but I can get an upgrade next month. Can I change my plan if I get an upgrade next month? Also, if I do this would I even be able to get the opportunity to haggle it down? And what would I even say? "Well I can get this deal from __ so unless you can beat that I'm leaving." ?
