off the Hook

Everyone knows the iPhone is great. Almost everyone wants one. But  for a business email user such as myself, you just can't beat the Blackberry for best-in-class messaging, calendar, and contact synchronization, and the J2ME model for custom applications is pretty powerful too.  The iPhone has some PIM options, but they all pale in comparison to the Blackberry. Why reinvent the wheel? In this world of increasing virtualization, how hard would it be to add Blackberry functionality to an iPhone, or at least emulate a Blackberry on an iPhone? Really? Both already run on the AT&T network, so that's conquered. Maybe I'm oversimplifying. It is late after all .
