I have 2 laptops on XP and the new one with Win7. My internet access is through an iPhone on a data plan connected to the Win7 machine by USB cable. This works fine. When the phone is disconnected I can wireless network the 3 laptops through a router but cannot when the phone is plugged in.
Is it at all possible to have what I want - the 3 laptops on my home network and the Win7 one connected to the internet through the phone at the same time?

Thanks, Brian S
