Still seeing the same old select copy/cut/paste issue in Safari here unfortunately. I was really hoping they would fix it finally.Seems like 8.2 has smoothed out landscape/portrait orientation and the select copy/cut issue on 5s.
Installing on iPad 2 as we "speak".
Spinning wheel in safari seems not to have been fixed.
As for spinning activity wheel in Safari, I'm still somehat split as to whether it's an actual issue or just some script or ad or something else that doesn't fully load on some pages that causes it.
