Knackered phone - any hope?

[lostkat]

I left my phone on the worktop next to the draining board a few months ago and unfortunately the draining board overflowed and knackered my phone. I didn't discover it until a few hours later, by which time it was dead.

I dried it out completely and have tried charging it up, but it's dead as a do do.

Is it worth me even trying a new battery or do you think the phone has had it?

It's a Nokia 5610. Nothing flash, but it's better than the K800i that I've had to go back to. Boo
