If you have previously "unbranded" your phone using the HKLM/System/Platform/DeviceTargetingInfo/MobileOperator "hack" this will not work - at least it didn't for me with a blank string. I kept getting "your phone is up to date" messages in Zune. Once I reset the string to 000-88 (which is still unbranded) it updated first try.
This is right, it's currently updating on my Telus branded Optimus 7, but I did have to set the MobileOperator registry key to 000-88.
