I’ve heard about the bad news for all 600,000 people who already pre-order the iPhone 4 that Apple will randomly canceled the shipment. But there is no strong data or confirmation from Apple or other iPhone 4 distributor about the issue and lately the rumors change with iPhone 4 is going to shipping earlier from the schedule (June 23th) . And again it still a gossip eventhough Engadget and other big website say so but they not yet get the ship notification email from Apple yet. Rumors can be juts dust in the wind, I think a lot of people have to a little bit patient waiting.
