Apple In-ear Headphones work fully with iPhone 3g s
They work perfectly for me. It does also list on the Apple site that they are compatable with the 3g s. Scroll down to the bottom right before the reviews.
Ha! I just discovered that the volume works on the 3GS today!
I was on the subway today and was trying to FF to the next song w/ a double click but must have hit hi because the volume turned up. I swear I gasped out loud like I just found a $20 bill at the bottom of my bag. lol.
