I currently have a wifi 16gb iPad and I use my android phone as a wifi hotspot. What I want to do is set my home wifi as the default wifi so that when I am out and about with my iPad, it uses my phone as a makeshift 3G connection, but when I go home it switches to my home wifi by itself to save my phone's data allowance. Is it possible to do this with IOS or can it be done with the iPad jail broken?
