iPhone 3G S Sales on Launch to Exceed iPhone 3G?

Despite the fact that the lines outside the stores are shorter than the iPhone 3G launch, the early sales numbers are indicating that the iPhone 3G S could exceed the sales of the iPhone 3G launch. This year, Apple and AT&T are allowing pre-orders for the iPhone 3G S which resulted in the shorter lines. Last year, Apple managed to sell up to 1 million iPhone 3G handsets on the launch weekend, but a UK Mobile Carrier called O2 has revealed that by lunchtime, they have sold more iPhone 3G S handsets than they did with the iPhone 3G for the entire day of launch. They are expecting to see 50% more sales than last year's iPhone 3G launch by the end of the day.
