Thanks to your awesome efforts, I made one myself. It was a little more what I was looking for. It's the iPhone ring, into white noise (as acard811 suggested), into the long Droid noise ringtone, into a little pause then DROOOID! It's about 8.5 seconds long. Let me know if you think the pause is too long. Also, let me know if you think I should make longer silence at the end.
OK, I attached the zip, too.
Edit: I added a second version. I think this one is better.
Second one:
iPhone > iPhone slowdown (dying) > white noise > Droid Mechanics > pause > DROOOID!
