AT&T late Friday said it had so far had its best iPhone launch ever after starting iPhone 4S preorders. The company had collected over 200,000 preorders just in the first 12 hours after opening up at midnight Pacific. It tried to credit the rush to its network, pointing out the "twice as fast" 14.4Mbps data and the inherent nature of the network letting calling and data co-exist at the same time.
