Explosion of iPhone sales in England

Following the drop in prices of the iPhone yesterday, a reader told us that Carphone Warehouse sold 3750 units in a single day instead of the usual 200.
To give a figure for comparison, the Nokia 2310 sold only 1250 units during the same day.
Knowing that each device comes with a subscription, it is excellent business for O2, which proves that Apple would have a real interest in allowing all telephone operators to subsidize their own sales of the iPhone.
