Thanks for all the posts & info.
Here's where I am now: I unlocked my SIM (donation) & flashed the 1.40WF Sprint Radio. I noticed slightly better SS (from 0-1 bars to 1-2 bars). I then flashed back to EnergyROM 28008, and the SS was the same (1-2 bars).
Then...under Phone Settings, CDMA Services, Network Service (not sure if this route is different under different ROMS), there is an option ("Home only" v. "Standard"). I changed it to Standard.
Now, when I place a call, my bars max out during the call. I'm not sure if this is really accurate, but the VQ seems to be better now. Weird...
EDIT: I think the home only v. standard is just roaming settings. Not sure. Okay, looks like I'm going to start a ticket with Sprint to complain, maybe they'll put up a tower a little closer? lol...
