Within 2 minuted of popping in the sim, battery and a miscro sd card full of music I had in my DSi, I called my wife in Finland. A minute later I sent my first tweet (http://bit.ly/5Wg6hj) while listening to some music. The first song I played on my N900 was funnily enough Major Lazer - "Hold The Line" http://bit.ly/d5Py9 "vibrate like a Nokia"
