And, if you're in Europe, you can thank the EU, who limited portable audio players to 150 mV max output at the phone jack and 100 dB (A) peak level with the included headphones.
This renders my iPhone almost useless as an iPod replacement when travelling with big headphones, it's just not enough juice for a train or bus ride (not to mention a flight).
wow, thanks for the info. lawyers - gah. still, no excuse for apple to limit the speakerphone...no one is at risk of hearing damage from a cell phone's speakerphone...you hear me apple?
