I got the update yesterday. So far so good. Seems the post activity drain has been fixed as well as the incorrect battery levels reported after charging. So far, I haven't noticed anything new since the 6.72 beta so I'm not sure if there is anything else to it.
I.m doing a manual upgrade to 7.10 now.
Just grab the GUPDATE.GCD from here: http://whiter.brinkster.net/generate...Firmwares.html
Dump it in your GARMIN folder
Take it off the USB cable and accept the install
Update: Installed fine. Booted, took a bit longer than usual on the loading maps part but finished. Watch is now on 7.10 and everything seems to be in order. Now closely monitoring battery consumption!
