The client iPhone app has now been submitted to the app store and is awaiting approval by Apple. The first version of the app will only have the basic functions of Boot, Shutdown and Reboot plus visible status indication. The app supports multiple virtual servers from different hosting providers.
We have also put together a small website to help your customers in using it. http://www.isolusvm.com
As a last note, we would like to thank Alex Blundell for his iPhone coding skills and making this app happen.
