I'd say you you have to kick in your brain right now, guys.. It's only logical, that you can't blame nokia, if your mobile sends 1000 sms spam messages in result of you intalling some 3rd party.. You simply can't sue nokia for such events - unlike on symbian, maemo apps aren't currently digitally signed, so it's a little hard to blame anyone really

You can however surely send N900 to a service, with full warranty, if you only installed a few apps from garage (or elsewhere) - and sometimes after that e.g. display suddenly stops working (even after reflash)..

I don't think that hardware is easily destroyable by using sw these days (well, maybe except for the flash memory) - and after reflash, nokia'd have hard time determining that the cause of hardware failure is in user-installed software anyway..
