purchasing new TP2 from Sprint(US) - any serial/revision to look for on phone or box?

[vancomycin]

Hey, are there any "newer/revised" editions of the TP2 since it first came out? I'm about to go pick one up from the Sprint Store, and I'd like to know if I should keep an eye out on the package/box labeling for anything in particular - i.e. a serial string / revision / letters / that might separate newer manufactured versions.

Or maybe something printed w/in the back of the actual phone itself would be better?

Other hardware devices have this at times, and I was wondering if this particular HTC TP2 went through such changes.... I couldn't find a good answer on this search query, so hopefully one of y'all might know. Thank you!

Oh, and should I expect the TP2 from Sprint to be preloaded with WinMo 6.5 or 6.1? I called a few stores and they gave me both answers.... obviously this was over the phone though

Cheers.
