Just got off the phone to Sky.... ADSL2+ is still a non starter!
My router syncs at 4992 now. When swapped to ADSL2+ is was at 4600.. plus the upload speed dropped a tiny bit (about 14kbps!)

So she swapped it back to G.DMT and it re-synced at 4992 again... that'll do me i 'spose. Well until 2015 when the UK becomes the No 1 place in Europe for broadband speeds! yeah right!

2015, the year i get 5000kbps

Thanks for all the info
