Nope. It's only for the 5G iPod and the nano. I, too, think 49 USD is a bit much for adding a remote (not really needed for the nano, anyway) and a tuner. I hope that the 6G iPod will have the tuner integrated, and if they can, the nano could have that feature also. But I don't think it's a necessity.
What I can't read anywhere, but I'm guessing: There's no recording option, right? That's a pity. The FM tuner would probably need to be integrated for it. But when I hear a song on the radio and want to later buy it, it helps to take a quick recording of it. Doesn't even have to be a really _good_ quality recording as long as I can guess the song title afterwards etc.
