Unlimited video recording with audio...

Once I was playing around with my friend's 7650...I was so shocked when I found that there is a Camcorder program in its phone which can record an unlimited length video with audio...!!! This is what I am looking for...I ask him where to get it but he said it is already installed in the phone when he took the phone for an upgrating... Does anyone know about this unlimited video recording software with audio?anyone one who knows please tell where to get it...thanks...
