iPhone/Safari won't quick scroll to top

[Anotoneher]

I've had my iPhone 4 for well over a year and about a week ago Safari quick scroll to top stopped working (when you touch the top of the screen and it auto scrolls back to the top).

I'm running 5.1, I've restarted the phone, dumped my cache/history in safari, hard-restarted the phone, etc. Problem persists. I have to manually scroll to the top of every single page in Safari.

Obviously this problem is unbelievably annoying. Any ideas? I've searched all over the internet and no one has a solution...

I have this same problem the scroll to top function in Safari won't or doesn't work anymore! Maybe someone has a solution. I'm jailbroken and in suspicious of activator but I've been jailbroken from the beginning years ago and never had this problem. I'm guessing it's a JavaScript error but don't know how to fix it other than restore which I'm about to do.
