why is apple the only phone it seems on the market that gives no option for personal hotspot tethering for optus on prepaid and i am sure many more phone companys. this option left up to the phone company to decide makes no sense to me they do not buy your phones the people buy your phones and if a cheep $100 dollar phone gives you the option to tether why cant apple.i have many friends with iphones on prepaid that have had to jailbreak there phone for this purpose alone.some have even gone and left apple to get a phone that can tether.please give a good reason or change please apple it will not make your phone unstable i am sure optus will still sell your phone because of the high demand i just cant work out why you have done this when every other phone has not.
