I just called CS to see if they could upgrade me from 3Mb to the 10(5)Mb service on my Samsung. They tried to send the upgrade signal but no dice - not accepting in my area.
Official line seems to be that its still in "pilot" mode for stb users and all existing 3Mb users will be auto upgraded by end of December. They said SACM users were more likely to be able to get upgraded over the phone as the technology is different.
C'est la vie.....
