Do you work at a large company that runs Exchange or a Cisco VPN? Have a secure WiFi network running 802.1x? Do you wish that your iPhone would play nice? Well, with today's announcements the iPhone will soon be a good enterprise citizen, but what if you can't wait until June? You can apply for the iPhone Enterprise Beta and help Apple iron out the kinks in the new software, and be the first kid on your block with ActiveSync on your iPhone.
No word on how Apple will choose who gets to be in the beta, but I am imagining it will be selective.
