Here's the page, which went live a few minutes ago:
The site is letting me buy the 'Pro', so it seems that there's plenty of stock this time.
See my in-depth two part review of the Wileyfox Pro, here and here on AAWP - it's a really neat little Windows 10 device and over-performs for what you might think given the raw specifications. The price looks high compared to Android offerings in 2018, of course, but then this doesn't really have any direct competitors. Businesses will buy these if they need a configurable and secure Windows 10 phone to hand out to employees and in such situations Android is way too open and insecure (for normobs), while iPhones are triple the price at least and won't match a Windows 10-centric business as well. Arguably.
For an end user, i.e. a generic AAWP reader, I'd still recommend the Alcatel IDOL 4 Pro at its current £320 from Microsoft - it's vastly more powerful, better screen, and has the monster speakers. But the Wileyfox Pro has a charm of its own that's not apparent until you've held it in your hand, taken it apart and generally appreciated the business use case.
PS. You may be wondering about an Amazon UK route for purchase too? Here's the search, which only comes up with Wileyfox Pro accessories right now. I'll keep an eye on it.
PPS. The eagle-eyed will spot on Wileyfox's site that they're now operating as a brand under Santok Ltd. I'm hoping to line up some kind of interview with the relevant people shortly.
