These units are GREY IMPORTS . They are unlocked but are Chinese operators sets so you wont get HTC support from them .
Expansys have deleted the threads that show this but you will see stock fluctuate as more people send them back.
I would show the thread but if you look at others its commented in there

Buyer beware they are falsly advertising this product as a UK version . IT IS NOT and you will not get support or warranty from HTC.
I would never buy from them again , not only is the cost high £500 but also they know about this and our trying to hush it up. Many buyers have called HTC and they have confirmed no support.
