I have BT total broadband with the BTHH 2 and am switching ISP but I like the HomeHub and was wondering if it was possible to use the router with a different ISP? I have read in the BTHH help that it is possible to change the username and password when the router is disconnected so would I be correct in assuming I just change this to the username and password my new ISP gives me and it will work? And I know that I wouldn't get firmware updates but I'm not really that bothered about getting them and I am guessing there are other ways of getting them.
