I'm starting to think that Nokia has it's days counted... The n900 is a great phone but the lack of decent apps currently and stories like yours everyday is making me to start to think that android is the best way to go...
Maybe there is some financial reasons for this, but Nokia should be ashamed of not providing support for its customers...
Can you contact nokia where you got the phone from and post it to them?
Another idea, is this damage something that you might be able to claim in your house hold insurance?
