The websites shipping to uk are saying 6h june, 9th june or 19th june.
I suspect that friday 6th june and monday 9th june are the same, and maybe the sites that got stock from the first supply to the uk. That sounds consistent with the sites saying 6th/9th, as they have had stock first with previous devices. The 19th June sounds like stock from the second round of supply to the UK.
I've pre-ordered from htcdirect.co.uk for the 6th, because i saw it before incino and a friend has used them before. I would probably recommend using inkino first only because they are listed on the htc page as official sellers.
