Can I install android os on my Nokia N8?
you can install android 2.2 froyo or druid 4 on a nokia n8 but nobody recomand you to do that just because you cand transform your phone into a brick. do to the hardware incompatibility, there is no official version made for nokia n8 so my advice is don't do it.
Unfortunately not. Many people have been wanting a port of android for the N8, but the ability to unlock the bootloader cane late, and developing drivers for the hardware, i.e. GPU, GPS, camera, etc., would have been very difficult and time consuming, if at all possible.
i doubt that for hardware reasons.
