Why do some people keep referring to this 1.2 as released in Hong-Kong but not the rest of the world ?
As far as I know it was shown on a device during a show in HK, at this time someone got hold of the beta FW and spread it around.

It is not an official release, not available for N900 buyers in HK or anywhere... so ?

If I was head of sw development @ Nokia I'd leak it and hope that the hackers & tweakers would test it.

I'd have a team following the "issues" & "bugs" and I'd let a few shills make postings like: "DON'T install this !", "ILLEGAL" & "Will BREAK and BRICK your device", etc.

In the mean time I'd have plausible deniability and get feedback from the die-hard fans of the N900
