I access the BIS website from my computer - My carrier for the Blackberry is AT&T. My internet service provider for the computer is Comcast or I can use Sprint (I have a U727 so I have wireless G for the computer too.) I have IE8 which was a problem on Symantec.com the other day - I was not able to input information and had to use another computer that had IE7 on it... that could be it - but who knows...
As I mentioned - I have desktop manager 4.7. I did find it weird that what the help menu said would happen in regard to inputting settings didn't.
