Blackberry got wet

How bad? Was it completely submerged or just a splash? If it was completely submerged, do not try and turn it on. Instead, remove the battery and place it in a jar full of dry rice to try and slowly remove the moisture. If that isn't an option try letting it sit in a dry, somewhat warm area for a few days. If neither option works, you're probably out of luck unless you have insurance through your carrier.
