speeds
quite sure BT hidden Monthly cap is around 100GB (if you do it over 2-3 months) very sure on BT option 3 as my friend was getting billed for going over 100GB an month on an 2-3mb connection lol
do consider you can do around 50-100GB an Day on virgin and not get shafted as much (not that i am asking you lot to do that thought as i like my 50MB fast as it is) yes you do have day limits but not that bad all they are doing is lowering the speeds for users that send to much (50MB) and slowing speeds down for 10mb and 20mb depending on download amount
bout time they uped the upload speed for 10mb users (256KB upload before cut back) as when that was nocked back 75% it was like 96kb {8-9KB/s} to slow for torrent's to work correctly and other services at the same time (like using the internet) as they need 128kb (or 10-15KB/s} to work (not an issue if your on 20mb as upload cut back was to around 200kb {20-25KB/s} so most users do not notice it)
if you are an VM user do note
they have Set the limits so they are download cap trigger takes aprox 15-20 mins to happen if your downloading at Full speed (not 50mb),
if your Uploading data at Full speed for aprox 30mins (it may be 1hr or longer now as they put the upload cap not far off the download cap limits guess they did this for legit P2P TV apps) that will also set the second trigger off unless the first one has all ready happened, if upload or download cap has been hit it affects Both upload and download speed for 5hrs from when it happened and can only ever be triggered once as it lasts for 5hrs (it can be twice if you did the morning trigger as well but that takes 2x longer to hit them caps aprox 30mins down @ Full rate)
(50mb not sure what happens to download speed, they better make sure it only affects the upload speed)
still there is no monthly cap on virgin services just daily limits that lower the speed (still think 75% is a lot thought on 10mb it is any way still you can still keep on downloading about 50gb an day even with that limit in place)

bt be funny if they do an 100gb cap on an 24-100mb service (when they say its unlimited again when its not)
BT Inifinity will be usable for Most of the UK as its FTTC (cab) not FTTD (Door or House) once its rolled out in your area's (1-5 years) if your Exchange is enabled for 21CN more likely to get it sooner then later (as the cables and fibre has been upgraded at that Exchange to support FTTC later on, as 21cn makes bugger all dif for ADSL1 or 2 users, FTTC is what its used for)
fibre to the cabs (or DP) in this case that's norm Only between 100yards (40-100mb users VDSL) or less then 500 yards away (up to 24mb ADSL2 tech avg most likely 15-20mb) from you all them poles goto an Point that norm Close to the streets they all merge up to that then goto the main Exchange the Fiber box going to be fitted next to the DP box where your ADSL or VDSL will be servied form if you take BT inifinity
