I tried to preorder an iPhone 4 online, but of course, I was one of the hundreds of thousands of potential buyers who could not get through the clogged Apple and AT&T servers on June 15, the first day the companies began accepting early orders. By the time the servers and system recovered enough to let me in, I was facing a “Ships by July 2” notice. Ouch. My buddy has it worse. His won’t ship until July 14. However, AT&T did get their shipments in on June 28, and they opened their doors to iPhone 4 sales the next day at 7 in the morning.
