Can't enable Hotspot since upgrading to 5.1.1
Hi I bought my iPhone 4S sim free and unlocked from Apple in January this year. I have previously used the personal hotspot on IOS 5.0, however I don't use it much as I have a 3G pocket hotspot. A month or so ago I upgraded to 5.1.1, today I had a need to enable my Hotspot and I find I cannot turn it on.
When I select "Set Up Personal Hotspot" I get a message saying ....
"To enable Personal Hotspot on this account visit http://www.vodafone.co.uk/help/iphone"
While the carrier is shown as Vodafone I am actually with BT Mobile who is an MVNO using Vodafone's network. So I can't sort it out with Vodafone because my account is not with them. The phone should not have any restrictions on it as I bought it outright, and this is something that has changed between IOS 5.0 and 5.1 because I have used this in the past.
Can someone tell me how to enable this feature, because while I don't use it very often I do use it.
Kind Regards

iPhone 4S, iOS 5.1.1
