To measure speed by accelerometer alone would be hugely inaccurate as you would need to take into account changes of direction and moving uphill etc. It just wouldn't be worth having.
The accelerometer measures rates of change of velocity and thats all.
GPS would be much more accurate, although it is possible to locate a phone by measuring the distance between three phone masts....but still not very accurate.

Well, The accelerometer measures the acceleration. And if you know the time and the amount of the acceleration during that time you can get the velocity.
m/s^2 * s = m/s
I cant see the hard part about it, but maybe the accelerometer isnt that accurate.

Yes i know that.. but if we do that all manually then no chance of getting even approximate value. The following file displays the acceleration produced in the handset
Acceleration Meter
so i think it is possible to make some kinda application that could measure the approximate speed.

Does the phone use the pedometer and a user entered parameter of stride length to work out distance/speed when walking/jogging?

is there any flash file or some java application for K850i which can be used as a speedometer (to measure speed of the moving vechile) by using its built-in accelerometer data???
I don't think it will work. At best it will give you a very, very inaccurate reading.
