I'm the same got mine from the car phone warehouse but with orange, our devices are unbranded and that means we should get the update direct from HTC, however it's just a waiting game as they are releasing the update in batches and it's just a waiting game as to when we receive the update.

 

My partner has the Samsung Galaxy 3 branded and he got his this morning.

 

The update has not rolled out in the UK yet, the last 2 updates were aprox. 10 days behind the rest of Europe. I have been told the networks in this country tend to delay the update rolling out to unbranded phones until they are satisfied with it. Personally i think it is so more people don't opt for unbranded than already do.
Myself i have used the RUU route & stuck 2 fingers up at the networks & got the update on time that way.

 

It has, ,my partner got it yesterday on his Galaxy3!!!

 

Samsung updates have diddly squat to do with HTC updates - they are different phones!
