it was released together with the launch of the N900. But the HongKong Version is an older Version of PR 1.2 like a different branch-line. Taken an early snapshot of PR1.2 and developed it further for the Chinese market (handwriting support and language support). Also the "PR1.2 RC" version floating around the web is not this version. This is even an older version of PR1.2 I hope this helped.
