Scrolling Stutter - 3GS

So, I've noticed that my 3GS 'stutters' when I try to scroll it. If I just flick it, no stutter, but if I move my finger up and down, stutter.

Anyone else having this problem? Is it a problem?

Thanks,

That worked, thanks. I'll play w/ it for a coupe of more days, and if it happens again I'll take a walk down to the Genius Bar. I need to go to the store anyway, as the charger they sent me doesn't work.

And, totally unrelated, I bought the Pre for Future Wife, and I really like it, but nowhere as much as this.
