I have noticed the upload speeds on T-mobile always seem to come up fast when I have treid speed tests
I have tried
The Bandwidth Place
Thinkbroadband
Speedtest.net ( By far the prettiest

) and they all report pretty consistantly on my broadband connection and my W & W connection
Here are my latest results on W & W
Date 11/02/07 08:57:00
Speed Down 158.74 Kbps ( 0.2 Mbps )
Speed Up 172.39 Kbps ( 0.2 Mbps )
......So my upload is faster that the download , lol !
There is one thing that makes me wonder , and I may be right off the mark here , but whan you have HSDPA Enable on W&W , it is put onto your account as "HSDPA 384K UPLINK" - is it possible that having HSDPA enabled faster upload speeds , even for those using vanilla 3G equipment ?
If anyone can tell me how to "test" this , I'd like to have a go !
