Hi mate
You should have a sticker underneath your 800 stating its a sim 2.01 or possibly Ferrari. If no its likely to be a bl72 version sim.
You could alway check the boot loader version of the image by disconnecting power then press and hold the standby button till it displays the bl version if it shows 75 you have a sim2 if it shows bl72 then you have a bl72.
