It looks like Apple's upcoming iPhone 4 is going to be a big hit.
The new totally redesigned model goes on sale June 24, but Apple started taking preorders Tuesday. In the first 24 hours Apple announced it had sold more than 600,000 new iPhones worldwide.
That's slightly more than 7 per second.
Demand for the new phone crashed servers at Apple's cellular partner and the company, too. Only the black model was available for preorder. A new white model will be available later.
Apple is already saying new preorders won't ship until mid-July, so looks like the best way to get one of these new phones is to stand in line at Wal-Mart or Best Buy or Radio Shack or AT&T or the Apple store at launch.
