Mine has been a mobile-only household for more than 6 months now and I'm rather reliant on it, which made it very interesting for me to see that according to my "Connection Information" on the modem client, my 3 mobile broadband service is now giving me a maximum 2MBit/s uplink and 8.6Mbit/s downlink. Of course the average speed crawls along at sub-50Kbit/s most of the time but previously the highest download speed was 3.6Mbit/s. A higher maximum would indicate some sort of network upgrade. I've tried disconnecting and reconnecting to see what maximum I get, but after 15 mins all I've had is (a par-for-the-course) 86Kbit/s uplink and 147Kbit/s downlink, during which time I've been downloading emails, browsing and uploading pictures to blogger. So the poor general performance of my mobile broadband prohibits me from double checking the results I received before. I'll investigate further.
