What is the name of the Violin Song for Sprint Commercials?

The song is called Nattoppet by Detektivbyrån. You can listen to it on their myspace: http://profile.myspace.com/index.cfm?fuseaction=user.viewprofile&friendid=62627043 The Classical Music from the latest Sprint commercial is "Unaccompanied Cello Suite No. 1 in G Major" by Bach. Wonderful piece!
