just updated to V40. smooth update for me. after update i notice the following:

-phone seems to reacts faster to inputs.
-audio seems a little louder
-Garmin and N.Maps works with no problem. Garmin can lock satellite pretty fast
-phone is easier to use with KS. scrolling thru contacts and inbox are much much easier now.
-Don't quite like the new HS with the big 'Telephone' written down there.
-Realplayer a little faster now

would recommend everyone to update the FW! KS really makes the phone easier to use.

tube much better with V40 right?

i just installed Vodafone HS. It's awesome.. I like it
