Trade-in your old iPhone for the 3G version? Yes you can, Orange France has release a limited amount of information regarding the new incentive program for at least their current customers that we know of. Weather this trade in incentive is available for new customers who are already owners of the iPhone is yet to be known. What is known is the cost to trade in the 8 or 16Gig iPhone to the 3G version would cost about £50(Euros) which at today’s exchange rate is about 75 bucks in the US. I'm sure we can expect to see other carriers following in the same trend in order to keep their current customers happy.
