I am trying to find the sensor size for N93 & N95.

I would love to know where I can find other detailed specs of the cameras beyond what is available in the techspecs from http://www.forum.nokia.com/devices/N93i ?

Also, does anyone know if the shutter speed can be controlled programmatically in these two phones ?

Is there any set of pages that has information specific to programming for a particular phone model ? eg: tell me what autofocus options are available for each phone ?
