Still there’s no new firmware update for the Nokia N900 available. However, a few selected contributors got the chance to test the upcoming firmware in advance. Unfortunately, this isn’t the big update all N900 user have been waited for. Portrait mode hasn’t been added in neither the internet browser nor in the entire menu. Anyway, PR1.1 should be faster and snappier and fix a bunch of bugs. As soon as the firmware goes public we’ll let you know.
