Customers swarm to buy the iPhone 4 outside an Apple flagship store in Beijing on Wednesday, Sept 29, 2010. The notice on the glass door reads, "No iPhone." The flagship store in Sanlitun abruptly suspended its iPhone 4 sales around 9 am on Wednesday and didn't reveal why sales stopped or when it would return to normal. However, it was reported that scalpers have snapped up a stack of iPhone 4s at the store and were reselling them at a premium. [Photo/CFP]
