Looks like the 8107 is finally getting rolled out to the Telus WP7 phones (at least the HTC Surround). Just plugged into Zune Desktop and down comes update 7740 and 8107
Update 2 patches within 30 minutes and rocking it now.
In case you need a reminder of what 8107 fixes, here's a link
I am testing out whether or not it fixes the Zune crash problem on the HTC devices (Problem remains - I'll keep poking Microsoft and HTC)
