Just tried out the Mobile Access Point setting that is available now with this update. Turned it on then checked my wife's ipad and it recognized a new network. Connected to it then I was sharing my phone's 3G internet. Lots better than having to pay extra for the Ipad with 3g and then on top of that having to pay extra to use 3g.
This should come in handy when we take our trip to Oklahoma later this year. We can have internet in the car on something bigger than a small phone screen.
