Just bought Windows Phone 8 Field Guide on Amazon got the PDF as well.
Only 3.6 for me as of 29/04/14 but it dose list one of the new features as.
Now looks great on large screen phones. Nokia 920
I really do like the look of it, but I don't like the look of the 360 so I guess its just my taste.
I have been using my 920 with the charging stand for some time never had a problem. The only thing is that the manual says if the phone is fully charged you get a long blink.
Just downloaded them all for my Nokia 920 in Australia. It did not show up on the store as an update had to find them manually. That may be because of the name change or as they were only released...
