I'm in Guildford and I use the NTL 250 SACM. I have tried ringing CS and asking for the upgrade but get told that it isn't available yet. I noticed that they did upgrade work in Guildford on the 7th so I tried rebooting my modem but I am still at the 3mbit speed. I've tried logging into the tier migration but it seems to get stuck at validating username?
