On earlier iPhones, there was a way to change a profile (?) file to make the non JB phone think that one was authorized by ATT to use data tethering without paying. is there such a solution available for the iPhone 4? At this point, the only compelling reason to jailbreak (in my opinion) is to share my data connection with iPad or laptop.
there is no simple file change... its JB or nothing and i don't think there is a way to share directly with iPad unless you tether to laptop then make your laptop broadcast a local wifi network
