Yeah, if that's the case, you're totally fine no matter what you do. It'll already have provisioned itself for Sprint, will accept all of the standard dialer codes for programming, and so on.

However, I want to warn you--the phone is SIGNIFICANTLY faster using 6.1/2.1. I'd forgotten how much snappier and responsive it was until I messed with a TP2 still running the old ROM. Custom ROMs will offer you more stability (sometimes), more glitz, more features, etc.--but they're not going to be faster. The TP2's best shot at having a fast, stable platform is probably Android. I've all but given up on having a pleasant experience with WM6.5/Sense2.5 on the TP2. (I may be unduly picky, though.)
