Here are the facts as I understand them (happy to receive corrections):Firmware originally came from inside Nokia (obviously) Firmware is not the same as the HK N900 firmware (no chinese support) Firmware was released on a chinese website Everything else is mostly speculation. We don't know when it left nokia. We don't know how long it took to get to the chinese website We don't know if it changed hands between Nokia and the website We don't know if it's version number is it's true version number or copied from HK N900 release number Is it right to slam those who installed it? No, the beauty of the N900 is it's openness the last thing we want to do is crack down on that. However those that do install it need to understand responsibility of their actions and try not to blame others if things don't go so well. Is it right to slam those who warned against installing it? No, as I said above we don't know where it's been and what it contains. It would be irresponsible of the community not to provide warnings. Should those who warned against installing then gloat when someone reports problems with it? Of course not, that's just petty and doesn't help. If you don't have anything useful to say then don't. Should people claim that this firmware is 100% safe? Of course not, because unless they are from Nokia or responsible for the leak they don't really know. Disclaimer: I've not installed the firmware as personally I would only want to install something officially from Nokia, however I've read with interest the new features and bug fixes that have been reported by those who did install and eagerly await an offical release.
