I understand it connects, but what is happening is the connection is being used heavily when there should be no activity on the connection.

As I said above, disabling the connection doesn't solve the problem, it just disables the problem. A problem that wasn't there 3 weeks ago. I had no problem running with the HSPA internet connection on.

I have since found out from another forum that another user has had this same problem. The only solution they found was to reflash and put all the settings in from the start.

Clearly then there is an issue and its not just limited to my device.
