Can you send songs from phone to laptop?

No. As of the time of this writing (02/02/2009), the iphone cannot send any attachments though email other than pictures. Furthermore, there is no official MMS, so you can't send them though text to another phone either.

i personally agree with that.... but my friends had their iphones.... and im not sure how it worked... but one of the girls phones was on searching for bluetooth, and the other girl had a song up on her phone, then they literally bumped their iphones together and it transferred the song to the other girls phone, ( they had the same version of the iphone tho). but i have no idea how that's possible....... but i watched it. so ya. :P
