hi thanks for your response.I am already aware that ip addresses for the following mobile broadband changes.
3 network ,T-mobile and 02 .
However for Virgin and Vodafone ,it doesnt change ,it always stays the same and I belive the fact that they might have assigned static IP to the device.
Therefore my concern was that ,if somehow I am able to change the physical address (MAC or the IMEI ) ,for the device then most probably this would be solved.
In neither of the previous threads ,this was resolved .If you know a thread in which solution for changing-mac for the mobile broadband dongle is given ,please forward it to me,
