Get the fuck out of here. I'm sure apple is just about ready to head right on over to Microsoft and bring them cookies so they can sit down and work this out.
If you work for a corporation that has an exchange server, no Activesync support kills the iPhone... I want one but no email and calendar sync no care.
The iPhone was never meant to be a business phone, and I'm quite sure that Apple really doesn't give a fuck about making it a business phone. It's selling well enough already.
