I'll do my best to explain this and I believe it's iOS 6 specific because it happens on my iPhone 5 and iPhone 4 and I noticed it right away after I updated to iOS 6. While viewing a web page in Safari in landscape mode, when you scroll down the page you can jump to the top of the page but touched the very top edge of the screen, right? So here is the issue (bug?) I found: If you're in landscape mode with the volume buttons on top, notice how far down on the screen you have to touch to make safari jump back to the top of the page. Now enter landscape mode with the volume buttons facing down. You'll notice that you can literally tap the side/edge of the phone and safari will snap back to the top. I find this annoying because I naturally turn my phone volume buttons up. I verified this with other phones in an Apple store too. I'm posting this here for others to verify and maybe some developers can report this Apple or is it a known bug? Thanks!
