How to make the light blink follow ringtones sound eg.like 5210??

So anyone of you guys here know how to make the Lights Blink Follow Those ringtones beat?

Do you guys know how to implant it into 8250/8210 or 3310?

I saw it in 5210 and others new mobilephone?

Please advise...........

u either can make them get brighter with each beat or make the leds only work when u play tones i am talking about the phone leds u can add an extra led and connect it to the buzzer or so it follows the beat and if u make the ringing sound highr the led will get brighter

I think that the 3315 upgrade will do this for a 3310 however i'm not sure

no the 3310-3315 will not do it sorry, however this is a trick that i like to do.
the current that passes through the buzzer is pretty high so you would only want to consider blue,white and purple leds for this job.
this is what i did for an 8210 i guess you could use it for any phone though.
put 4 white leds in each corner position and in the 2 middle positions get tape over the solder pads with some sticky tape and glue either 2 blue or purple leds on top of that. then just wire up the blue leds to the buzzer.
so you have a white screen normally but it flashes blue when the phone rings.
it looks really good and makes sure you use really bright blue leds
