Yahoo Messenger for iPhone and iPod Touch (.ipa)

Yahoo Messenger finally hits the Apple Appstore. Its a really good app, and makes me wonder , again, how one can pull such a good client for the iPhone and the one on the Macs absolutely SUCKS? You can get Y! mess for the iPhone and iPod Touch for free from the iTunes store or you can download the .ipa file from rapidshare in case it is not available in your country.
