I asked O2 prior to the 4S launch if there'd be any discount for upgraders. They told me that they couldn't say until after the launch (had a 3gs for over 2 yrs on contract). After launch they said "no-one ever gives discounts for upgrades on iphones". So good luck. I was however able to get a cheaper, better deal over 2 years by buying the phone straight from apple and getting a sim-only dea - not from O2l. If you tot up the figures over the life of a 2 year contract yourself for all the mobile operators there's virtually no point in getting a carrier locked phone from them.. if you have the cash to spend outright on the phone in the first place.
