After 40% - 50% discount with free shipping, most items are under $10. I am interested in a delux earphone with earbud and a microphone for iphone, after discount is $12 shipped. Anybody have an iphone, knows whether the jack is the same for n800?

It's reported to be the same, except that the iPhone plug is just a little longer than standard, so you have to pull it ~1 mm out of the jack; then the mic and both channels are all said to work.

Obviously, if it's cheap enough, you can afford some time making a spacer or similar; a few ideas were tossed around for that.
