Not a stupid question at all. For what you want, voice and texting (with, I assume, email and some light browsing), I can't see any reason not to go with a "newer" 3G phone (Droid X2, Incredible 2, Droid 3, etc.) that doesn't require flashing. If it turns out you want to do more (which would be ?... I'm not quite sure what) then you could always buy a newer phone and flash it. Right now I'm using a Motorola Admiral on RingPlus and it's a big step up from my XPRT only because it has more memory. That why I suggest something in the newer 3G phones, they started getting more RAM with each release and that's a big help.

Again, I'm not a huge Internet user, nor do I engage in "social networking" so maybe that would make the difference.
