Disclaimer: Please don't flame for not figuring this out through search I have a question on tethering. I have a jailbroke 4.1 iphone and I would like to purchase a new ipad2 and get wi-fi and avoid getting a service plan 3g one. Can I purchase my-fi for my phone and then use just a wifi Ipad2 for internet access? Will this work. Will the speed be fast enough?
