Can the little whites who are using 3.0 confirm that the message can be forwarded?

SMS and MMS can be forwarded directly,

Packet forwarding video/audio MMS Because the iphone does not support video recording yet,

So you can't send video MMS directly. The recording can be sent directly by MMS. Because iphone doesn't allow programs other than ipod to access mp3 music synchronized through itunes,

So you can't send mp3 music directly.
