585V6 Firmware

[#1]

My exchange will be going live with ADSL2+ end of the month, and I have applied for the trial.
I have looked around, and think the most up to date firmware for this model is the 6.2.T.2,  but seen on a speedtouch partner forum that there is a 7.4.3.2  Has anyone used this, or the 6.2.T.2  I am on 6.2.16.3  which is very stable for me.  Would welcome any advice

Check out the DMT page on http://www.kitz.co.uk/routers/DMTv7.htm
If your present firmware supports ADSL2+ then don't update (unless you have reason to do so).

Thats the issue axis..... Not sure if my firmware supports ADSL2+.  If it does, then I will not change, as very stable.
