Music-based social networking site Last.fm has introduced a native application for iPhones and iPod touches. The program presents a simplified way of listening to personal, recommended and other radio streams on the site, as well as keeping tabs on items such as friends, charts and upcoming concerts. Items with a red dot indicate that they can be streamed; when tracks are playing, album art is displayed in the background.Tracks can be recommended to other people through e-mail addresses on a person's Contacts list, and when browsing sites in Safari, the app will launch after clicking "lastfm://" links. The current drawback to the software is that because the iPhone 2.0 firmware does not allow background processes, launching Safari will force Last.fm to halt entirely. The app is a free 0.3MB download.
