Jason Murray has been testing this for a while, and this is his feedback "I just wanted to say thanks for your info on the personal hotspot within our iPhones !!! I have an iPad which I was very fortunate to be given, however it was only wi-fi enabled, restricting me to web surfing and checking mail at home. Now with the ability for my iPhone to act as my own personal wi-fi hub I can take my iPad everywhere, and use my iPhone's Internet connection. This is a fantastic leap forward, thanks so much for putting it out there and sharing it with us."
So thanks to Jason for this feedback. Obviously, it works well and I encourage more of you to try it.
