Well if it's any consolation to those of you still waiting my upgrade has resulted in a fairly stable service. I am receiving a steady 9.5+Mb downstream and 470+Kb upstream...( well unless I hit the stm

) so maybe you will find it's worth the wait.
Keep checking back to this thread and if you do get your upgrade don't forget to let everyone know. Oh and feel free to have a moan if it helps, we know what it's like to wait in the dark.
