I have purchased a new iphone5 and had to upload the latest version of itunes to enable syc so that I could load data.
The "Personel Hotspot" did come up and I could use it as a modem alright.
Then did a reset on the phone as I didn't want the new phone to be a clone of the old phone.
Since then I have not been able to use the new iph5 as a Personel Hotspot.
Please Help Geoff.
Verify that your carrier supports Personal Hotspot for your device and that you have Personal Hotspot enabled on your cellular plan:
