I flashed this about an hour ago and have been setting it up, for me the only bug I have found so far is that ovi store does not show my stuff the circle keeps spinning

but I can still download from ovi store because I downloaded swype, so far it seems stable but I can't comment on the purple screen , however the standard lock screen does look better in terms of colour but I'm colour blind so the purple tint really does mean nothing to me.
The new calendar is good, transitions are good. In the camera app theres a new icon on screen to take photos.
The latest nokia bubbles works realy well with it, no more 2-3 second lag when pressing the menu key to get bubbles to show
I've loaded up best task manager and there appears to be more ram available, sweet, i'll have to keep an eye on this though.
All in all so far now I have tweeked my N8 I'm glad I have flashed it, but If your all expecting miracles from anna in the UI then personaly for me it's not there, I'm expecting that in Belle.
I'd recommend that you all should flash this and give it a go, I don't think it's the final release of anna because there is no split screen but it's still worth a flash.
