Sorry if these or one of them was already said but I have been testing this out since the first iPhone update. Two things I noticed different since the update that, to my knowledge, have not been posted here: When you pull your ear phones out of the iPhone while music is still playing, it does not automatically start playing out loud. I like this bc if I pull them out I do not necessarily want my music blasting out loud with people around. Also, before the update my girlfriends iPhone and my iPhone both would not play in our two different car iPod systems. It said that this device would not work with this accessory and if we wanted to go in airplane mode. Hitting "no" or "yes" would not do anything but play the music off the iPhone loud speaker. Now after the update, both our iPhones work on both different accessories and play on the car loud stereo. If these were not mentions, try it out, and let me know, at-least for the car one because I am interested if they fixed this. If someone already mentioned these let the flamming begin!
