Try pushing it through email.

I wanted to know if there is a way to push data to a IPhone. We have a Dedicated Windows 2008 server hosted with Server Intellect and looking to install some software that will allow us to push schedule updates and documents to our employees and clients. We don't want them to have to connect to the server, we want to be able to control when they receive the data and get a response back that data has been received, and we need it for a Windows Server 2008 OS. Any ideas would be greatly appreciated. Thanks!
