So I jumped from a 2G iPhone to a 3GS on release day. I used the old phone occasionally for the iPod but mostly listened to Pandora. Today is the first day I am using the iPod feature on the 3GS and noticed something weird. I have my auto screen lock set at 1 Minute, but the screen never officially locks as long as I have the iPod program up. After about a minute or so, it goes into the very dim power-saving mode and then just sits there. When the song changes over, the screen goes to the normal in-use brightness. Even on very long songs it will sit on the dim screen and never actually lock. This is not something I ever remember experiencing on my 2G iPhone, and I could not find any clear options regarding this in either the auto-lock or iPod setting menus. Is this standard behavior now? EDIT: The same behavior is happening while playing the iPod and looking at my SMS messages. The screen will never lock and will go back to normal brightness when the song changes in the background.
