I have an iphone 4 with an unlimited plan (lucky me!) and am very curious about tethering. What is the easiest, best method to turn my phone into a mobile hotspot? I have done an internet search and most of the pages with tips and pointers are out of date. I saw that Tether just got taken off of the App store.. Bummer. What is the best thing to do? Jailbreak? Tether App? What is an unlimited data plan gal to do?
