And, somehow "brilliant" idea by Nokians - if any component in N9 turn out to be like famous "USB port broken issue", they won't need to replace anything and listen about how user want phone repaired, not other model as replacement. They will just check (unclearable, without bricking device permanently) records of flashing kernel, and answer "warranty void!".
And yes, I'm probably biased, cause even reading about such a nonsense make me somehow sick. Don't get me wrong - I'm glad people are getting closer to jailbreak it, but, honestly, I don't see point. It's like taking generic Android phone, and rebuilding everything from scratch for years (probably), just to get something working "closely" to what N900 offers now (closely, but never at the same level!).
