the v220 ad i cant fully remember but it ends with a guy dancing in the middle of a road, with parked cars either side of him, he's dancing to a ringtone/background music that im searching for, and he stops dancing,flicks his phone open and walks away saying 'my moto'. thats just the ending tho.
the sony ericsson ad is where its symmetrical all the way throughout the advert, one half is a girl and the other is a gy, and they meet at the end and it shows the phone, and how it seperates. the tune is a gradual one, starts simple and eventually incorporates a beat etc.
