That really is good sound from a phone!
My old Motorola Droid (yes, the original) phone doesn't do quite as well but placement may have been a factor. Here's a video I took with my phone just sitting on my music stand. Thus, "The Singing Head". http://www.youtube.com/watch?v=ZpS7bVYuURc
We were in the green room at a club goofing around and a friend took this one on his Galaxy phone. http://www.youtube.com/watch?v=MGboVgc5gzM
Smart phone videos, good idea for a thread.
Thank you for your indulgence,
