I've been seeing a bug with 3.0 with regards to the iPod playback function in the 3GS iPhone 3.0 and I'm wondering if anyone else has seen it or reported it yet. When on the music playback screen I see the lower playback bar (with the play/fwd/back arrows) periodically jump down several rows of pixels and then jump back. It has the appearance of almost trying to hide at the bottom of the screen and then jerking back up to its normal location. Has anyone else seen this? It's kind of annoying and on a few occasions seems to prevent the auto dimming from working properly. Thanks.
