Hi All, here I have question to ask, please help...If I use a separately device (the voltage source of this separately device also from the hand phone battery) to activate the vibrator, is it possible? Thanks!

please help...

Yes it's possible.

Thanks!!! Then who able to provide me the Nokia 8250's circuit diagram? Possible to get it from Internet? I can get it so far... please help...

You will find VERY few modern commercial products that have schematics available. Basically if you can't figure it out on your own no one else is going to help you because you haven't made the first step to discover how your circuit functions in the first place. Asking for help is NOT the first step to self education.
