Steve Jobs is calling it Apple's most successful product launch ever -- 1.7 million iPhone 4's in the first three days. Pretty amazing. That works out to a rate of 7 phones per second. Of course, Apple is having trouble meeting this demand, and is now saying that new orders will take three weeks to ship. You can read a brief report on Macworld, as well as see the press release on Apple's site. I'm expecting mine to arrive tomorrow!
