I upgraded to the 3.0 firmware and now its as if the speaker doesn't exist. It won't make any noise except through headphones, when I press the volume buttons, nothing happens, even on the screen. And when I listen to music or watch movies, the volume bar disappears unless headphones are plugged in. This is a major pain because I have always used my iPod as an alarm. Anyone else have this problem? BTW, I do have an iPod Touch 2G and it worked perfectly before the upgrade.
