One of the main reasons I wanted to jailbreak my iPhone was to be able to scrobble the tracks I played on my iPod to my last.fm account.  I really love last.fm, both for the radio features and just to have a history of what I’ve been listening to.  I like to track my habits, “love” certain songs in last.fm to remember them, and discover new music by playing artist stations (in a similar manner to how I use Pandora).  I hate having to remember to sync my iPhone just to scrobble things, so when I found out you could auto-scrobble directly to last.fm AS you used your iPod, well…let’s just say it didn’t take me long to break my iPhone out of the slammer.

Now, with iPhone 3.0, there is an application called iScrobbler that allows you to scrobble directly from your phone.  You add your music (as much or as little as you want) and listen to it from inside the app.  As long as the app is open, your played tracks will be scrobbled.  Not as elegant as a small application running in the background…but it’s a start. According to a post in the last.fm forums about the app, you can also start playing tracks on your iPod, and as long as you start the app before the first song ends, it will scrobble that track and all tracks played until the app is closed.

I have downloaded it, but not used it yet.  My biggest complaints so far are that I really hate the color scheme–it is an inelegant mix of orange and yellow that quite frankly hurts my eyes–and the track information (artist, album, title) is in a very small font.  But, like I said, it’s a start.  I look forward to seeing this app grow and possibly seeing something cooked up that will allow background scrobbling in iPhone 3.0.
