I am currently trying to figure out how to reverse tether a G1 to use an ad-hoc computer-to-computer network. I have Internet at work through ethernet and created an ad-hoc network, but the built in G1 wireless scanner cannot detect ad-hoc networks. There is an application in the marketplace called Wifi Scanner which can detect adhoc networks but it does not have a connect feature. I tried to manually connect using ifconfig in terminal but havent been successful yet. I’ll post updates if I make progress.
