Increasing ring since 0-volume

[avengerx]

I am used to a Sony Ericsson Z-530i where 'increasing ring' means:

1. Vibrate for (approx) 3 seconds.
2. Vibrate and low sound for more 3 seconds;
3. Vibrate and moderate sound for more 3 seconds;
4. Vibrate and loud sound for more 3 seconds;
5. Vibrate and OUT LOUD sound for the remaining of the time.

If I disable vibration, it starts from step 2.

If I set initial ring volume to minimal (0), the phone treats it as absolutely mute and there is no ringtone at all during all time increasingring should be doing its job.
It would be great if, instead of going from current volume to max volume, there were an option instead to go from zero volume to the current volume. I am not very experienced yet on making android thingies but I hope this is not an too hard thing to do! :)

Thank you!
