Success in business is largely about taking credit. Just ask the co-founders of Twitter. Or, more accurately, those who say they're the co-founders of Twitter. It is said, indeed, that Steve Jobs used to take credit for too much at Apple. But now that he's gone, a new creditor has stepped into the limelight he so appears to enjoy. Donald Trump, he whose name is on hotels and the "Celebrity Apprentice," seems to be taking credit for Apple's latest iPhone. True, no one's actually seen Apple's latest iPhone. But Trump revealed on Monday that he knows what's coming. And what's coming has been thanks to the deep and influential pressure he has massaged and kneaded into Apple CEO Tim Cook. In a tweet that was a forthright as it was human, Trump wrote: "I wonder if Apple is upset with me for hounding them to produce a large screen iPhone. I hear they will be doing it soon -- long overdue."
