At a recent Citrix Application Delivery Conference in Melbourne last week, Citrix used its thin client desktop software, XenDestop, to demonstrate an iPhone running Windows XP. Using the Citrix ICA client — a UNIX application that allows devices to access Windows sessions on a Citrix server — the presenter was able to run Windows on the iPhone via Wi-Fi.

Of course, we’ve seen a jail broken iPhone with the capabilities to VPN into a windows running machine, but now Citrix appears to be offering a program that will allow you to do this without unlocking your iPhone.

There is no specific release on the option; it is still being tested and demoed on the phone. The good news is that this option will be relatively inexpensive compared to the corporate versions offered by Citrix in the past.
