have just spoke to HTC customer service:08458900079 very helpful. they said unbranded (meaning no network logo) handsets although locked to networks, update will be via HTC they are rolling out the update is drifts.
I have not been one of the lucky ones to have had the first drifts of update
but just have to be patient they said, but it is out.
Customer service is brilliant.
