The first five numbers are not unique. First two are the factory it was manufactured in, second one is last digit in the year and the last two are the week it was manufactured. For example, 87(factory)0(2010)26(26th week of 2010). The rest of the serial number is unique to each device.

It won't be double digits. A digit followed by an alphabet character. I have no idea what they mean though.

100% false.

I had 9 replacement 3G's (don't ask).... all were refurbs out of black boxes. 4 had "normal" serial numbers. 5 had 5k's.

The ones that weren't 5K's were new phones used for replacement devices, not actual refurbs. They always have to do this for at least the initial month or two of release, when there are no refurbs yet.
