Telus tech support resolved my problem, I have EVDO data now. Unfortunately, after flashing back to the Telus ROM for the tech support people and then flashing to MightyROM once I verified on the Telus ROM that stuff was fixed, MightyROM appears to be misbehaving quite badly.
I think I'm just gonna go back to stock Telus ROM for a bit and see if I can set it up how I like it. Thanks again to all who offered help.
edit: yay. Did a hard reset, flashed back to stock Telus, did another hard reset, flashed to MightyROM, did ANOTHER hard reset, configured it, and all appears to be working right, fingers crossed
. Thanks for the work on the ROM, Mike, it feels excellent!
edit again: sent a lil donation.
