Vibrate switch not working.

[galanoth]

Got a 3GS on launch day.
Dropped it a couple times a few month after.
Some dings but no performance damage.
Last weekend when putting the switch to vibrate, it auto switches to ring
while the switch is in vibrate mode.
How much do you think it would cost for a fix?
thanks

You can bring it to Apple and see if they'll replace it for free.
Or send it to a repair shop.
This place will do it for $35
