Ok, more questions for the PPC geeks!

Looking to tweak my phone a little. I don't have a big name carrier, in fact my phone gives no indication whatsoever of the carrier, no label on the phone, no name on the boot up screen. All my screen says during bootup is HTC, some numbers across the bottom (haven't looked close, but I think they are my ROM info, etc.) and then the WM boot screen. My carrier is Nex-tech Wireless, and occasionally I will see NTW in the upper right hand corner of the home screen. Any suggestions for good tweaks that are good for all carriers, or any way to determine which ones I am safe using? My current info:
ROM version: 1.08.573.1 Date: 2/18/09
Radio version: 1.01.15F
Model #RAPH800
Pretty sure I have a CDMA carrier (no sim card).

Any suggestions are appreciated!
