I've just been playing around in the installer app and came across something strange. I was looking at PDFViewer in the utilities section and clicked on the more info link. This brought me to an unformatted file list section instead of an info page. I clicked on the OtherErica folder link and scrolled to the bottom where there was an MP3 file called Voice.MP3. I clicked on it and the screen went haywire as it loaded the file into the quicktime movie player, the file played OK but when I hit done the screen went mad again with lots of flickering and image ghosting. I didn't leave it in that mode for very long as I was afraid of it damaging the iPhone (no idea what was going on but it didn't look good), pressing the home button took me back to the springboard and installer launched again without any problems. Has anyone else experienced this or have any idea what is happening?
