ok i unlocked my first gen iphone last night and got some apps.

shazam is amazing, it is voodoo black magic. basically, if a song is playing on the radio or television and you do not know who it is by, just open shazam and it listens to the song for 12 seconds then it can identify it. i was sceptical but it works beautifully.

secondly, the remote control app is also very clever, you can use it to control your itunes music from the iphone. seamless, and without hesitation. truly cool.

and both free.
