TP2 Build Revision Identification options.

[Sarc]

So, another thread had the question come up, "Is there a way to identify a build revision on any specific TP2?"

I figured instead of muddying up another thread, I would start this one to see if any ideas/info could be formed to possibly do just that.

I took a photo of the back of mine under the battery, but till I know which numbers are safe to post, since things like the IMEI and the like are not a good idea to share, I'll hold on to them.
That said, there are a few numbers that make me think they might be referencing a build revision, just not sure.

Another question I brought up in the other thread, was do all TP2's (from Sprint at-least) have a plasticy feeling touch screen? Or did some feel as they might be glass?
