I know the official Froyo has not been released, but I see here that you can Install it on samsung phones: http://androidforums.com/samsung-galaxy-lite/251507-update-android-2-1-eclair-2-2-froyo-your-samsung-gt-i5800.html But there it mentions
I5800XXJPF I5800XXJPB
but does not mention I5800XXJP3
so is it possible, if so, how?
