I am a new android user and just recently purchased the Samsung Infuse with AT&T. I'm looking for a tethering solution. I would like to set up tethering from my phone to mac laptop however, 1) I'd like to be able to set it up so I don't initially need a separate internet connection for the laptop to prepare everything to tether, 2) am trying to avoid having to subscribe to AT&T's monthly tethering plan, and 3) am trying to avoid having to root my phone in order to do this. Does anyone have any suggestions? Is there an app that would allow me to set up tethering just by connecting my laptop via the USB cord without having to subscribe to AT&T and without having to download anything onto the Laptop first?
