Wireless networking an iPhone 3G?

Hello,

I wonder if anyone can give me help in setting up wireless network to an
Apple iPhone 3G? I have two computers networked via Lan connections on a
Netgear DG834GSP modem/router. I have just set up the wireless section
and the iPhone can connect via Wi Fi, I would like to be able to see the
iPhone on the two PC's and be able to drag and drop files as I can
between the two computers. Any help much appreciated or even point me in
the direction of any useful information.

Thanks
Gerald
