I've discovered a scroll issue with the LongListMultiSelector (The Windows Phone Toolkit, I have yet to reproduced it with the LongListSelector).
The problem seem to arise when you have a list of items with images that is of different sizes or takes some time to load.
The isssue is when you scroll to the bottom and try to scroll to the top after that you will not reach the top but a couple of items before the top item. The list thinks you are at the top.
I've attached a sample project. (Follow the link to codeplex)
(The first time I tried to post this issue my wifi died so this post is shorter, hope you understand the issue)
Steps to reproduce:
Start the app on device. (not reproduced on emulator)
Before the list has loaded the images, start to scroll quick to the very bottom.
At the bottom, wait a second or two.
Then start to scroll to the top.
(If you have reached the top, close the app and goto step 1.)

Is this a bug or am I doing something wrong?
I have a published app with this issue so any help is appreciated since the users has started to notice this issue.
