I carried a BlackBerry for work for years and was an early tester of the iPhone for my employer. They issued the iPhone 4 to a few volunteers to test out with our email system etc. I found it to be way better than the Blackberry. If they had forced me back to the BlackBerry I probably would have found a new job. And, a huge number of colleagues who saw me using it at work got excited and put in requests for their own iPhones. It was just so much easier and more pleasant to read on the iPhone.
