The wi-fi only version of the iPad has convinced me to look into jail breaking my iPhone, so that I can tether the two and use the data plan I’m already paying ATT for. I know the app I need on the iPhone is MyWi from the rockyourphone app store, now I just need to find jail breaking software that works on iPhone 3.1.3 OS, since most that I’ve seen say they don’t work on anything above 3.1.2
