I know this thread is about the iPad, but I just wish ATT would allow the iPhone to be a hotspot with the 3GB data plan. I'm paying for the limited data, who cares how I use it? There is not a tethering charge, but why is it only available with the higher data plan? I don't necessarily want or NEED to go over 3GB, even with tethering. I'm going to get throttled if I use too much one way or the other.
