This is my first video with my iPhone4. The HD is very sufficient for in pocket recording. This collaboration was pretty cool because it was all apple. You can see the two macs in the video, which were used to play a loop of the music while the 4 people thought of their lyrics. And Kat wrote her lyrics on the white mac, mike on the black mac, reg on the iPhone4, ray on the newest iTouch and I recorded it with my iPhone4.
