The iPhone supports VPN connections, allowing you to connect to your Igaware server remotely, and it also supports a neat little app called NetPortal (also available on the iPad called FileBrowser). These apps allow you to access your files on your server, open them, save them to your iphone of email them.
Creating a VPN connection is easy on the iPhone:
Go to Settings => General => Network => VPN
Configure a PPTP connection:
Once configured you simply launch the VPN connection in Setttings => VPN and then launch NetPortal.
So if you want to access your files anywhere, the iPhone and Igaware make a great combination. You can also achieve this with other smart phones.
