Should I give up on VOIP?

[RjG]

Been searching and reading threads all day here (and elsewhere) trying to get VOIP / SIP working on a PPC6700 (CDMA Bell )
I upgraded to Apache WM6.1 Kitchen CE OS 5.2.19716 (Build 19716.1.0.0) from WM5, no problem.

SipConfigTool_2_0_1.CAB let me set up my VOIP account.

Found a couple versions of WM6VoIP.CAB, none did anything for me.

apparently there is some problem with CDMA phones and the "Today" plugin? I don't even know what that is, or how that affects VOIP functinoality, lol.

Anyway, problem is I don't see the "internet" tab on the PHONE settings screen. And it's not selectable from the DIAL screen. I've seen 1/2 dozen other posts about that too here, read them all, but no solutions were posted on any of them either.

I don't use this phone anymore, and my goal was to turn it into a WIFI VOIP phone. So will I blow it up if I flash it with, say, SPRINT as the carrier instead of BELL? So it gets a GSM style flash? Will that make the VOIP part work properly? Or brick my phone forever?

Like I said, I've been messing with this for over 8 hours now. If anyone has some clues, I'd SURE appreciate it.
