finally I installed Android Ginderbread 2.3.3 on n900 but I expected it was better that what i found

it's slow dunno why, is there something i can do ?!

and the camera isn't working !! is it normal or I'm having problems

and will I miss other features ?!!

thnQ

For the official release (which I don't think is Gingerbread, though the functionality is probably about the same), you can see what is/isn't working here.

I've not noticed any particular performance issues with Nitdroid (general use - I've not dried any games, etc), but I've never used a real Android device, so I wouldn't notice any difference.
