I own an unrooted Droid and I would like to be able to tether it to my wife's iPod touch for internet access away from a wireless router at home. I'd like to do the same tether between my phone and my lap top while away from home. I've obtained the app PDAnet on my Droid as a starting point. Will I need a connection cable or can this be done wirelessly? Anyy assistance would be appreciated.
