Let me phrase the question differently- just as "food for thought" for all those critical of the OP.
How many of you, that didn't flash their phones - because they are responsible people - followed the threads of those who did, in order to try and see whether it worked and what is good and bad about FW1.2?
If you did, aren't you building on the experience and gumption of those who had the guts to try? Are you hoping that any bugs that were exposed by those who tried will be fixed by Nokia before the release?
So why be self-righteous?
