Dry it thoroughly then disassemble and clean all electronics parts with PURE alcohol or cleaning benzine and Q-Tips. Don't be too shy with the liquid, esp if it was Sea/Saltwater.
I had similar probs with my N95 and this cured it.

Open it. Clean it. Put it in a jar of rice for 3 days.

Bury the rice in the north side of the yard.

Last step is optional.

Done that, now. But only using Ovi Suite 3. Will probably try again with a full flash.

Oh, and just as I did last time - cause apparently I don't learn from mistakes - I forgot that the backup of applications isn't done by the backup function in Ovi Suite. My previous backup using the backup application on the N900 was from May. Yay.

I will open it a third time when I get time, and see if I find anything to clean up. But there's nothing left to dry up any more. Also, it's been said that the rice is a myth.

replace, THEN take it to nokia service center...


Actually if you look on page 2, it looks like there may even be wifi modules avaiable...?

Yes, seems like. But from what I've seen, I'm guessing that is but a few mm large... I wonder how much it'd be to get it repaired outside of warranty.

Edit: i sent a request to a local repair shop, hopefully I'll get a price from them.

Ach doch! They had closed down the Nokia repairs part. I might try a mechashop elsewhere, though.
