New Firmware Version 1.02.12 for the My Book World I & II (10/19/11)

I’m just wondering about the file size of the new firmware update.  I currently have no internet at home due to changing ISPs so I only have my phone data.  I downloaded the firmware installer which mentions about downloading modules for the firmware.  Anyone know how big the firmware upgrade ends up being?

I just don’t want to start the process and then realise the download is too big, thereby forcing me to cancel the ungrade midway, potentially corrupting my NAS.

Any info would be great.  Even an estimate.

Thanks.
